Abu Al-Tufail says that once I asked Sayyiduna Ibn Abbas (may Allah be pleased with them), "Your people think that the Prophet (peace be upon him) performed Sa’i between Safa and Marwah while sitting on a camel, and that this is Sunnah?" Sayyiduna Ibn Abbas (may Allah be pleased with them) replied: "These people say something correct and something incorrect." I asked, "What is correct and what is incorrect?" He said: "It is correct that the Prophet (peace be upon him) performed Sa’i while sitting on a camel, but it is incorrect to consider it Sunnah. In reality, people would not move away from the Prophet (peace be upon him), nor could they be made to move, so the Prophet (peace be upon him) performed Sa’i while sitting on a camel. If he had not been on a mount, walking on foot would have been more beloved to him."
