It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that she said: The Messenger of Allah (peace and blessings be upon him) came to me, and he (peace and blessings be upon him) had (already) performed ablution. I offered him (peace and blessings be upon him) some meat on the bone, or shoulder meat, and he (peace and blessings be upon him) ate from it, then stood up for prayer and did not perform ablution again.
