Sayyiduna al-Fadl bin Abbas (may Allah be pleased with him) was riding behind the Prophet (peace and blessings be upon him). He said that on the evening of Arafah and the morning of Muzdalifah, when the people began to set off, the Prophet (peace and blessings be upon him) said: "Keep to tranquillity," and he (peace and blessings be upon him) was holding back his she-camel, until he entered Muhassir, which is part of Mina, and he (peace and blessings be upon him) said: "Take small pebbles, the kind with which the Jamrah is stoned." the Prophet (peace and blessings be upon him) kept saying the Talbiyah until he stoned the Jamrah.
