Is it permissible to perform Salah

Q 2: Is the following statement a Hadith: "Offer Salah behind any Imam even if he is a dissolute profligate one"

A: We know no Hadith of the same wording. However, the notion can be found in the Hadith narrated by (Part No. 7; Page No. 379)  Mak-hul from Abu Hurayrah (may Allah be pleased with him) who said that the Messenger of Allah (peace be upon him) said, Striving in the path of Allah (Jihad) is incumbent on you along with every ruler, whether he is pious or impious; the Salah is obligatory on you behind every believer, pious or impious, even if he commits grave sins. Recorded by Abu Dawud and Al-Daraqutny. However, it is a Hadith Munqati` (a Hadith with a missing link after the Follower; the generation after the Prophet’s Companions) as judged by Al-Majd ibn Taymiyyah: "Mak-hul did not hear the Hadith from Abu Hurayrah." Quotation ended.Moreover, Al-Shawkany said, "The Hadith of Abu Hurayrah is also recorded by Al-Bayhaqy which is Munqati` likewise. It is also recorded by Ibn Hibban in Al-Du`afa' (Weak Narrators). In its Sanad (chain of narration) there is `Abdullah ibn Muhammad ibn Yahya ibn `Urwah who is Matruk (a narrator whose Hadith transmission was discarded due to unreliability). Furthermore, it is recorded by Al-Daraqutny as reported by Al-Harith on the authority of `Aly (may Allah be pleased with him), as reported by `Alqamah and Al-Aswad on the authority of `Abdullah and as reported on the authority of Abu Al-Darda' through chains of narrations all of which - as judged by Al-Hafizh - are very weak. Al-`Uqayly said, 'Of the text of this Hadith there is no reliable chain of narration.'" The liberal quotation from Al-Shawkany ended. For more details about the subject, consult the book Nayl-ul-Awtar by Al-Shawkany Vol. 3, p. 199 and subsequent pages and the book Al-Maqasid-ul-Hasanah p. 267.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
