She cannot pray tahajjud because her baby daughter cries; will she be rewarded?
Question

                I have a small daughter 18 months .Im breast feeding her.I used to always get up for Tahajjud and i find myself at peace when i pray it.But last few months even though i get up before time my daughter gets up the same time and im not able to pray it.this is happening everday.I am getting very dissapointed and wonder why Allah is not helping me to pray.My husband is not very supportive for even Fajr prayers and also my baby insists that i take her.She cries profusely.Im in a very difficult situation right now and i need Allahs help.I pray and do dua nd zikr but i find peace in Tahajjud.I also have to repent a sin which i do in night prayer.Im wondering why i cannot pray and whether Allah is angry with me so he is not allowing me to pray.I do dua to wake me up,i wake on time ,do wodu and then over....Plesae guide me.
Praise be to Allah.
      Qiyaam al-Layl is one of the best of deeds and acts of 
      worship, and the one who misses out on it should grieve and feel sorrow. 
      But if a person is sincere in his intention and is resolved to get up, and 
      takes measures to help him to do that, but then something prevents him, 
      such as the crying or screaming of a child, then there is the hope that he 
      will attain the reward of qiyaam, because of the hadeeth of Abu Moosa (may 
      Allah be pleased with him), according to which the Prophet (blessings and 
      peace of Allah be upon him) said: “If a person gets sick or travels, the 
      reward for what he used to do when he was at home and healthy will be 
      recorded for him.” Narrated by al-Bukhaari (2834). 

    Al-Haafiz Ibn Hajar (may Allah have mercy on him) said: Thuis 
    refers to one who used to do an act of worship then was prevented from doing 
    it, and his intention was that if it was not for that impediment he would 
    have continued doing it, as is mentioned clearly in a report narrated by Abu 
    Dawood via al-‘Awwaam ibn Hawshab, with this isnaad of the report of 
    Hushaym, at the end of which it says: “… like the best he used to do when he 
    was healthy and at home.” That also appears in the hadeeth of ‘Abd-Allah ibn 
    ‘Amr ibn al-‘Aas, which is attributed to the Prophet (blessings and peace of 
    Allah be upon him): “If a person is doing well in worship then he becomes 
    sick, it is said to the angel who is appointed over him: Record for him (a 
    reward) like that of the action he used to do when he was healthy, until I 
    make him healthy or take him to Me.” Narrated by ‘Abd al-Razzaaq and Ahmad; 
    classed as saheeh by al-Haakim, al-Albaani and the commentators on Musnad 
    Ahmad. Ahmad narrated a hadeeth from Anas which he attributed to the 
    Prophet (blessings and peace of Allah be upon him): “If Allah tests a Muslim 
    with some calamity in his body, Allah says: ‘Record for him his righteous 
    deeds that he used to do.’ If He heals him, then He has washed him and 
    purified him, and if He takes his (soul, in death), He will forgive him and 
    have mercy on him.” [Classed as hasan by al-Albaani and the commentators on
    Musnad Ahmad]. … According to the hadeeth of ‘Aa’ishah which was 
    narrated by al-Nasaa’i: “There is no Muslim man who prays at night then is 
    overcome by sleep or pain, but the reward of his prayer will be recorded for 
    him and his sleep is a charity for him.” [Classed as saheeh by al-Albaani]. 
    End quote from Fath al-Baari. 

    If the one who usually prays qiyaam al-layl is overcome by 
    sleep, the reward for his prayer will be recorded for him. So it is more 
    likely -- in sha Allah -- that this applies to the one who wakes up but is 
    not able to pray because of their baby’s crying. 

    Hence we say to our sister: Be of good cheer and hope for 
    grace and reward with Allah, may He be exalted. Renew your intention every 
    night and resolve to get up, and take measures that will help you to do 
    that. Then if you cannot pray because your baby is crying, you will still 
    have the hope of attaining the reward in full, in sha Allah. 

    If your husband cannot get up to pray qiyaam al-layl, or he 
    is not interested in doing that, then perhaps he can sleep next to the baby 
    when you get up to pray, so that she (your daughter) will feel that there is 
    someone next to her. 

    You could also put her in a small crib beside you whilst you 
    are praying, and rock her if she cries, or put your hand on her whilst you 
    are praying, if that will calm her down. 

    Or you could pray whilst carrying her, if you are able to do 
    that whilst standing, or you can pray sitting and holding her, if you are 
    able to do that. 

    With keenness and sincerity of intention towards Allah, we 
    hope that Allah will make it easy for you to do what you love of acts of 
    worship and divert distractions away from you. 

    Part of the etiquette of the believer with his Lord is to 
    think positively of Him. It was narrated that Abu Hurayrah (may Allah be 
    pleased with him) said: The Messenger of Allah (blessings and peace of Allah 
    be upon him) said: “Allah says: ‘I am as My slave thinks I am and I am with 
    him when he calls upon Me.’” Narrated by al-Bukhaari (7405) and Muslim 
    (2675) 

    So think positively of your Lord and remember that He will 
    reward you and give to you, and that He will guide your daughter and help 
    you to pray qiyaam al-layl; do not think that He is angry with you or is 
    diverting you from the honour of standing before Him. 

    We ask Allah to increase you in love for qiyaam and tahajjud 
    and to help you to do that. 

    And Allah knows best.
