Musannaf Ibn Abi Shaybah 13611 — Tawaf on a mount: those who permitted

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) came while he (peace and blessings be upon him) was suffering from an ailment, so he performed tawaf riding a camel. He (peace and blessings be upon him) had a crooked staff with him, and whenever he passed by the Black Stone he touched it. When he (peace and blessings be upon him) finished his tawaf, he made the camel kneel and dismounted, then offered two rak'ahs.
