‘ Ab? Y?suf once said that one may not perform Sal?tul Khawf after the prophet’s ( - ) death and claimed that people followed the prophet ( - ) in this Sal?t for the superiority of following him ( - )’. Then he commented on Ab? Y?suf’s view saying: ‘This view does not hold water for the prophet’s ( - ) Sah?bah performed it after the prophet’s ( - ) death one of whom was Huthaifah ( - رضي الله عنه -) in Tabaristan and many others too famous to be mentioned here’. (1)

Having narrated Ab? Y?suf’s view regarding Sal?tul Khawf, one of the ‘Ulamah said: ‘Ab? Y?suf may have meant that Sal?tul Khawf was done in one congregation at the prophet’s ( - ) time only, and after his death many congregations were formed for doing it. All?h knows best’. (2)

At any rate, many evidences affirm the legality of performing this Sal?t and some ‘Ulamah even reported the unanimous agreement on this point, no way of denying this Sal?t. (3)

Evidences also affirm the legality of performing Sal?tul Duh? (4) and it’s being a Sunnah.

[2/ 67] Some held the illegality of doing Suj?dush Shukr though it is affirmed to be done by Al? ( - رضي الله عنه -) when he found Thuth Thadiyyah killed amongst the Khaw?rij, by Ka‘b Ibn M?lik after he received the glad tiding of being forgiven by All?h ( - عز وجل -) and the whole event is narrated in the two “Sah?hs” (5) and by Ab? Bakr when he received the news of killing of Musailamal Kathth?b.

None, who has sound sense, would doubt in the legality of doing Suj?dush Shukr considering the authentic Ah?d?th and the righteous Salaf’s practice. (6)
