Umm Salamah (may Allah be pleased with her) said: I complained to the Messenger of Allah (peace and blessings of Allah be upon him) that I was ill, so he said: "Perform Tawaf riding behind the people." So I performed Tawaf, and the Messenger of Allah (peace and blessings of Allah be upon him) was praying in a corner of the Ka'bah. He was reciting Surah At-Tur.
