(58) باب إِذَا حَضَرَ الْعَشَاءُ فَلاَ يَعْجَلْ عَنْ عَشَائِهِ
Narrated `Amr bin Umaiyya:
That he saw Allah's Messenger (ﷺ) cutting a piece of mutton from its shoulder part he was carrying in his hand. When he was called for prayer, he put it down and the knife with which he was cutting it. Then he stood up and offered the prayer without performing new ablution.
