His parents want to separate, and each of them wants him to be on their side
Question

                My parents are in the moment of getting divorced through court. My mothers statement in the court contains lies according to my father. As well as my father's statement in the court contains nothing but lies according to my mother. Now my mother wants my help to tell my father to stop spreading fitnah, and my father wants my help too to say the same thing to my mother. As a son, I can't pick a team. I know that my mother is not 100% to be blamed for her statement and neither my father. but Allah knows best. I don't like the way they both getting divorced by neglecting the way that Allah and His Messenger SAW already prescribed in the Quran and Sunnah. I have tired many times to give them advice, showing them the truth but nothing as the result. Can you please give this son some advice on what he can do as a muslim son in this situation and to help him get rid of the feeling of being helpless.
Praise be to Allah.Honouring 
	one’s parents is a duty that is enjoined on children, and disobeying them is 
	something that is definitively forbidden. Allah, may He be blessed and 
	exalted, says (interpretation of the meaning):
“And your 
	Lord has decreed that you worship none but Him. And that you be dutiful to 
	your parents. If one of them or both of them attain old age in your life, 
	say not to them a word of disrespect, nor shout at them but address them in 
	terms of honour.
And lower 
	unto them the wing of submission and humility through mercy, and say: ‘My 
	Lord! Bestow on them Your Mercy as they did bring me up when I was small.’
Your Lord 
	knows best what is in your inner-selves. If you are righteous, then, verily, 
	He is Ever Most Forgiving to those who turn unto Him again and again in 
	obedience, and in repentance”
[al-Isra’ 
	17:23-25]. 
Shaykh 
	Muhammad al-Ameen ash-Shanqeeti (may Allah have mercy on him) said: 
In this 
	verse, Allah, may He be glorified and exalted, enjoined sincerity of worship 
	to Him alone, and He mentioned alongside that the command to treat parents 
	kindly. This pairing of obedience to parents with worshipping Him alone that 
	is mentioned here is also mentioned in other verses, such as the following: 
“Worship 
	Allah and join none with Him in worship, and do good to parents…”
[an-Nisa’ 
	4:36] 
“And 
	(remember) when We took a covenant from the Children of Israel, (saying): 
	Worship none but Allah (Alone) and be dutiful and good to parents…”
[al-Baqarah 
	2:83] 
“Give 
	thanks to Me and to your parents, unto Me is the final destination”
[Luqmaan 
	31:14]
Elsewhere, 
	He explains that honouring them is obligatory, even if they are mushrikeen 
	and call one to join them in their shirk (association of others with Allah), 
	as He says (interpretation of the meaning):
“But if 
	they (both) strive with you to make you join in worship with Me others that 
	of which you have no knowledge, then obey them not, but behave with them in 
	the world kindly”
[Luqmaan 
	31:15] 
“And We 
	have enjoined on man to be good and dutiful to his parents, but if they 
	strive to make you join with Me (in worship) anything (as a partner) of 
	which you have no knowledge, then obey them not. Unto Me is your return”
[al-‘Ankaboot 
	29:8]. 
In these 
	verses Allah, may He be glorified and exalted, mentions kindness to parents 
	in conjunction with Tawheed (affirmation of His Oneness) and worshipping Him 
	alone. This is indicative of the emphasis placed on the obligation to treat 
	parents with kindness.

	from Adwa’ al-Bayaan, 3/85 
Hence it is 
	obligatory for you to honour your parents, treat them kindly, offer them 
	sincere advice, and try to reconcile between them. If they insist on 
	divorce, the right of either of them to kind treatment is not waived, no 
	matter how wrong they have been. 
You should 
	explain clearly to them that you will continue to honour them and will try 
	hard to be kind to them, but you will avoid inclining to either party at the 
	expense of the other or listening to claims and accusations that may turn 
	you against one or the other, as there will be no benefit in listening to 
	these claims if they have chosen to separate. 
You should 
	remember that the mother’s right to good companionship is three times that 
	of the father, without detracting from the father’s rights. 
It was 
	narrated that Abu Hurayrah (may Allah be pleased with him) said: A man came 
	to the Messenger of Allah (blessings and peace of Allah be upon him) and 
	said: O Messenger of Allaah, which of the people is most deserving of my 
	good companionship? He said: “Your mother, then your mother, then your 
	mother, then your father.” 
Narrated by 
	al-Bukhaari, 5626; Muslim, 2548. 
An-Nawawi 
	(may Allah have mercy on him) said: In this hadeeth we see the 
	recommendation to treat relatives kindly, and that the mother is the most 
	entitled of them to that. Then after her comes the father, then the next 
	closest, then the next closest. The scholars said: The reason for precedence 
	being given to the mother is the great deal of effort that she puts into 
	raising him, her compassion, her service, the difficulties she suffers in 
	pregnancy, childbirth, and breastfeeding, then in raising him, serving him 
	and taking care of him when he is sick, and so on. Al-Haarith al-Muhaasibi 
	narrated that the scholars were unanimously agreed that precedence is given 
	to the mother over the father in terms of kind treatment. Al-Qaadi ‘Iyaad 
	narrated that there was a difference of opinion concerning that: the 
	majority said that she is given precedence but some said that the parents 
	are to be given equal good treatment. And some of them attributed that to 
	Maalik. However the correct view is the first opinion, because of the clear 
	meaning of these hadeeths. And Allah knows best.

Shaykh 
	Muhammad ibn Saalih al-‘Uthaymeen (may Allah have mercy on him) was asked: I 
	am a young man, twenty-five years of age. My father and mother are 
	constantly arguing all day long. If I show kindness to one of them, the 
	other one gets angry, and if I show kindness to the other one, the first one 
	gets angry and accuses me of being disobedient. What should I do, O shaykh, 
	in order to honour both of them? Am I regarded as being disobedient towards 
	my mother just because I show kindness to my father, or vice versa? 
He replied:
The answer 
	in this case is that honouring parents is one of the most important duties 
	that one human being owes to another, because Allah, may He be exalted, says 
	(interpretation of the meaning): 
“Worship 
	Allah and join none with Him in worship, and do good to parents…”
[an-Nisa’ 
	4:36]. 
“And your 
	Lord has decreed that you worship none but Him. And that you be dutiful to 
	your parents”
[al-Isra’ 
	17:23]. 
“Give 
	thanks to Me and to your parents, unto Me is the final destination”
[Luqmaan 
	31:14]. 
And there 
	are many hadeeths that speak of this matter. What the individual is required 
	to do is to honour both of his parents, both his mother and his father, and 
	to treat them kindly financially, by means of physical actions, by means of 
	his high status, and in every way he can. Allah, may He be exalted, says 
	(interpretation of the meaning):
“And We 
	have enjoined on man (to be dutiful and good) to his parents. His mother 
	bore him in weakness and hardship upon weakness and hardship, and his 
	weaning is in two years give thanks to Me and to your parents, unto Me is 
	the final destination.
But if 
	they (both) strive with you to make you join in worship with Me others that 
	of which you have no knowledge, then obey them not, but behave with them in 
	the world kindly”
[Luqmaan 
	31:14-15]. 
So He 
	enjoined kind treatment of these mushrik parents who strive to make their 
	child follow them in their shirk; despite those efforts on their part, Allah 
	commands the child to behave with them in this world kindly. As that is the 
	case, what you have to do with regard to your parents who you say are always 
	arguing, and that each of them gets angry with you if you show respect to 
	the other, is two things: 
Firstly, 
	with regard to the disputes that are occurring between them, you should try 
	to reconcile between them if you can, so as to put an end to the disputes, 
	enmity and resentment that existed between them. That is because each spouse 
	has duties towards the other that must be fulfilled, and part of your 
	honouring your parents is to try to put an end to these disputes so as to 
	clear the air between them and make life happier. 
Secondly, 
	your duty towards them is to honour and show kindness to each one of them, 
	and you can deflect the anger of the other when you show kindness to one of 
	them by concealing it. So you can show kindness to your mother in some way 
	that your father will not find out about, and you can show kindness to your 
	father in some way that your mother will not find out about. In this way you 
	will have done what is required of you. You should not be content to let 
	your parents remain in a state of conflict and dispute and you should not 
	leave them in such a frame of mind that they will get angry if you show 
	kindness to one of them. What you have to do is explain to each of them that 
	showing kindness to one does not mean that you are severing ties with the 
	other; rather each of them has a share of kind treatment as enjoined by 
	Allah.

If your 
	parents persist in this dispute, what we think you should do is avoid 
	getting involved in their arguments altogether, especially since you have 
	been offering your advice to them from the beginning. 
May Allah 
	help you to honour your parents and guide you; may He guide your parents and 
	set their affairs straight. 
And Allah knows best.
