Sayyiduna Abu Hurairah (may Allah be pleased with him) said: I was with Sayyiduna Ali ibn Abi Talib (may Allah be pleased with him) when the Messenger of Allah (peace and blessings be upon him) sent him (to Mecca). He made four proclamations until his voice became hoarse: Listen, O people! Only a Muslim soul will enter Paradise, and after this year, no polytheist shall ever perform Hajj, nor shall any naked person circumambulate the House of Allah, and any covenant between any person and the Messenger of Allah (peace and blessings be upon him) is valid for four months; after four months have passed, the covenant of Allah and His Messenger is ended.
