يَوْمَئِذٍۢ يَتَّبِعُونَ ٱلدَّاعِىَ لَا عِوَجَ لَهُۥ ۖ وَخَشَعَتِ ٱلْأَصْوَاتُ لِلرَّحْمَٰنِ فَلَا تَسْمَعُ إِلَّا هَمْسًۭا
On that day they follow the summoner who deceiveth not, and voices are hushed for the Beneficent, and thou hearest but a faint murmur.
Surah Taa-Haa(20:108)

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.
