Al-Bukh?r? narrated that Ibn ‘Umar did Sal?t behind Al-Hajj?j Ibn Y?suf Ath-Thaqaf?.
Im?m Muslim and other Sunnan compilers reported that Ab? Sa‘?d Al-Khudri did Sal?tul Eid behind Marw?n who delivered the Khutabah before doing Sal?t and took the prophet’s ( - ) pulpit out of the prophet’s ( - ) mosque [and hence deviating from the prophet’s ( - ) Sunnah].
Ash-Sahwk?n? said: ‘The Sah?bah and those who followed them agreed practically -and their verbal agreement is not an impossibility- that doing Sal?t behind the unjust Im?ms is permissible since the Sal?t Im?ms during their time used to be the rulers themselves. This was during the Umayyad’s reign whose rulers were well-known of being Tyrants’.
See: “Naylul ‘Awt?r” (vol. 3 / p. 200), “Majm?‘ Fat?w? Ibn Taymiyyah” (vol. 1 / pp. 108 - 9), “Al-‘Ilal Al-Mutan?hiyah” (vol. 1 / pp. 418 - 9) and “Jannstul Murt?b” (p. 273).
53 - ‘Sal?t is the main pole on which religion rests, whoever establishes it, has indeed established religion and whoever abandons it has indeed caused religion to destruction’.
The aforementioned had?th is commonly used by the preachers when teaching people about Sal?t and the great status it occupies in Isl?m. I have never read such a had?th [in any had?th compilation] in the aforementioned wordings, except a narration narrated by Al-Baihaq? in his “Shu‘ab” (vol. 1) which states: ‘Sal?t is the main pole on which religion rests’. This narration is traced back to ‘Ikrimah Ibn Amm?r from ‘Umar Ibn Al-Khatt?b from the prophet ( - ). Having mentioned this narration, Al-Baihaq? reported his Shaik’s, Al-H?kim, statement: ‘Ikrimah has not heard [any had?th] from ‘Umar. In his “Mushkilul Was?t”, Ibnis Sal?h said: ‘It [i.e. the had?th] is unknown’. And in his “At-Tanq?h”, An-Nawaw? said: ‘This had?th is Munkar and B?til [false]’. Commenting on An-Nawaw?’s statement, Al-H?fith Ibn Hajar said in “At-Takh?sul Hab?r” (vol. 1 / p. 173): ‘It is not so. The had?th was narrated by Ab? Nu‘aim -Al-Bukh?r?’s Shaikh- in the chapter titled “As-Sal?t”
