صحيح مسلم

Simak asked Jabir b. Samura about the prayer of the Apostle (ﷺ). He said: He (the Holy Prophet) shortened the prayer and he did not pray like these people then, and he informed me that the Messenger of Allah (ﷺ) used to recite" Qaf. By the (Glorious) Qur'an," and a passage of similar length.
