Zaid bin Yathi’ said: We asked Sayyiduna Ali (may Allah be pleased with him): With what message did the Messenger of Allah (peace and blessings be upon him) send you? He replied: I was sent with four things. First, that only a believing soul will enter Paradise; second, that no one should perform Tawaf of the House of Allah naked; third, that after this year, disbelievers and Muslims will not gather together for Hajj; fourth, that the Messenger of Allah (peace and blessings be upon him) and whoever has a treaty with him for a specified period, their treaty will remain for that period, and for those whose treaty has no specified period, they are given respite for four months. He says that after the Day of Sacrifice, they were given respite until the twentieth of Dhul-Hijjah, after which the command was that after four months, they should be killed.
