It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that she said to the Prophet (peace and blessings be upon him): I have not yet performed the Tawaf al-Sadr (farewell circumambulation). He (peace and blessings be upon him) said: "When you have prayed, perform the tawaf behind the people, riding on your camel."
