The hadith “At the beginning of every century Allah will send to this ummah someone who will renew its religious understanding”
Question

                In Kitaab al-Mulaahim by Abu Dawood, it says that the Prophet (blessings and peace of Allah be upon him) said: “At the beginning of every century Allah will send to this ummah someone who will renew its religious understanding”. Is this hadith saheeh? Who narrated it? Is the Muslim obliged to believe this hadith?
Praise be to Allah.
	This hadith is one of the well-known, saheeh hadiths; it was 
	narrated by the great Sahaabi Abu Hurayrah (may Allah be pleased with him) 
	from the Messenger of Allah (blessings and peace of Allah be upon him), that 
	he said:

	“At the beginning of every 
	century Allah will send to this ummah someone who will renew its religious 
	understanding.”

	Narrated by Abu Dawood (4291); classed as saheeh by as-Sakhkhaawi 
	in al-Maqaasid al-Hasanah (149) and by al-Albaani in as-Silsilah 
	as-Saheehah (no. 599).

	What the Muslim is required to do is to believe in the saheeh 
	hadiths of the Messenger of Allah (blessings and peace of Allah be upon him) 
	and accept them, with no hesitation about what is said in them. This is one 
	of the requirements of belief in the Messenger (blessings and peace of Allah 
	be upon him). Allah, may He be exalted, says (interpretation of the 
	meaning):

	“O you who believe! Obey Allah 
	and obey the Messenger (Muhammad (blessings and peace of Allah be upon 
	him)), and those of you (Muslims) who are in authority. (And) if you differ 
	in anything amongst yourselves, refer it to Allah and His Messenger 
	(blessings and peace of Allah be upon him), if you believe in Allah and in 
	the Last Day. That is better and more suitable for final determination”

	[an-Nisaa’ 4:59].

	Mujaahid and others of the earlier generations said:

	“refer it to Allah and His 
	Messenger” means: referring to 
	the Book of Allah and the Sunnah of His Messenger. This is a command from 
	Allah, may He be glorified and exalted, stating that regarding every matter 
	concerning which the people may dispute, having to do with both fundamental 
	matters and minor issues of religion, the dispute concerning that must be 
	referred to the Qur’an and Sunnah, as Allah, may He be exalted, says 
	(interpretation of the meaning):

	“And in whatsoever you differ, 
	the decision thereof is with Allah (He is the ruling Judge)”

	[ash-Shoora 42:10].

	Whatever ruling is given and testified to by the Book of 
	Allah and the Sunnah of His Messenger is the truth, and what can there be 
	beyond the truth except misguidance?

	The scholars have interpreted this hadith soundly. They said: 
	The word “man” (translated here as “someone who”) is a relative pronoun that 
	in general in application. It may be that the renewer (mujaddid) is an 
	individual or it may be a group of people. Based on that, it is not 
	necessary to seek out the names of individual scholars at the beginning of 
	every century and determine who among them is the best in order to decide 
	which of them is the renewer (mujaddid), for they may all play a part in 
	renewing religious understanding and spreading it among the ummah.

	Al-Haafiz adh-Dhahabi (may Allah have mercy on him) said:

	What I believe concerning this hadith is that the phrase “someone 
	who will renew its religious understanding” 
	should be understood as plural, not singular. End quote from Taareekh 
	al-Islam (23/180).

	Ibn Katheer (may Allah have mercy on him) said:

	A number of scholars said that the correct view is that this 
	hadith includes every individual scholar in any given age who takes on the 
	communal obligation of conveying knowledge from those whom he met of earlier 
	scholars to those whom he meets of the coming generation, as it says in the 
	hadith narrated via mursal isnaads and others: “Among successive 
	generations, this knowledge will be transmitted by the trustworthy and 
	honest, who will defend it against the distortions of the extremists and the 
	fabrications of the promulgators of falsehood.” This has continued, praise 
	be to Allah, until the current time, and we are in the eighth century.

	Al-Haafiz Ibn Hajar (may Allah have mercy on him) said:

	This does not mean that at the turn of every century there 
	will be only one; rather it may refer to a group, and this is something that 
	makes sense, for the fields in which renewal is needed are not limited to 
	one type, and it is not necessarily the case that all the good qualities 
	required (to bring about this renewal) will all be found in a single 
	individual. However that may be the case with regard to ‘Umar ibn ‘Abd al-‘Azeez, 
	for he was in charge of the ummah at the end of the first century and the 
	beginning of the second century, as he combines all the good attributes and 
	virtues, and was ahead of others in that regard. Therefore Ahmad stated that 
	they used to interpret the hadith as referring to him. As for those who came 
	after him, for example ash-Shaafa‘i – even though he had many beautiful 
	virtues and attributes – he was not in charge of jihad and establishing 
	justice. Therefore, anyone who had some of these attributes and virtues at 
	the beginning of a century may be among those referred to in the hadith, 
	whether there are several such people or not.

	End quote from Fath al-Baari (13/295).

	Moreover, it is not necessarily the case that if a person 
	meets the description of the renewer (mujaddid), Islam will prevail in his 
	time, or that the Muslim state will have the upper hand. The renewer may be 
	in the field of knowledge, not in the field of leadership and politics; 
	indeed renewal may be in the field of da‘wah, education and the like. This 
	is how we may understand the words of the Prophet (blessings and peace of 
	Allah be upon him) “someone who will renew its 
	religious understanding”, as being 
	general in meaning (and not specific).

	On the basis of this understanding, we do not think that 
	there should be any confusion in the questioner’s mind concerning the 
	meaning of the hadith.

	The Standing Committee said:

	What is meant by the words of the Prophet (blessings and 
	peace of Allah be upon him, “someone who will 
	renew its religious understanding”, 
	is that every time many people deviate from the path of the religion which 
	He perfected for His slaves, completed His favour upon them and chose for 
	them as their religion, He sends to them scholars or a scholar who has deep 
	knowledge of Islam, and a wise caller who helps the people to develop a 
	proper understanding of the Book of Allah and the proven Sunnah of His 
	Messenger, and protects them from innovation and warns them against 
	newly-invented matters, and brings them back from deviation to the straight 
	path of the Book of Allah and the Sunnah of His Messenger (blessings and 
	peace of Allah be upon him). This is called renewal of the ummah (tajdeed 
	al-ummah), not renewal of the religion that Allah prescribed and perfected. 
	Changes, weakness and deviation happen time after time to the ummah; as for 
	Islam itself, it is protected by means of the protection of the Book of 
	Allah, may He be exalted, and the Sunnah of His Messenger (blessings and 
	peace of Allah be upon him), which explains the Book of Allah. Allah, may He 
	be exalted, says (interpretation of the meaning):

	“Verily We: It is We Who have 
	sent down the Dhikr (i.e. the Qur’an) and surely, We will guard it (from 
	corruption)”

	[al-Hijr 15:9].

	Al-‘Allaamah Hammood at-Tuwaijri (may Allah have mercy on 
	him) said:

	As for interpreting the hadith as referring to a few specific 
	individuals at the beginning of every century, or one of them, that is very 
	unlikely and the hadith does not indicate that, because the word “man” 
	(translated here as “someone who”) may refer to the singular or the plural. 
	Based on that, interpreting the hadith as referring to a group of scholars 
	who take it upon themselves to spread knowledge and renew religious 
	understanding is more appropriate than interpreting it as referring to a 
	single individual, after whom there will come another single individual.

	This is supported by the report that was narrated by at-Tirmidhi, 
	who classed it as hasan, from ‘Amr ibn ‘Awf (may Allah be pleased with him), 
	according to which the Messenger of Allah (sa) (blessings and peace of Allah 
	be upon him) said: “Islam began as something strange and will go back to 
	being something strange, so glad tidings to the strangers, those who will 
	correct what the people corrupt of my Sunnah after I am gone.” 
	

	It is also supported by the report which was narrated by Ibn 
	Waddaah from ‘Umar ibn al-Khattaab (may Allah be pleased with him), 
	according to which he said: Praise be to Allah Who has blessed people by 
	sending after the Messengers people of knowledge who call those who have 
	gone astray from guidance, bear with patience their harm and bring people 
	back to their senses by means of the Book of Allah… 

	This indicates that the renewal of religious understanding 
	may be done by a group of scholars, and is not limited to one at a time. End 
	quote.
