Ibn Uthay said that he asked Sayyidina Ali , “With what were you sent (by the Prophet (SAW))“ ?‘ He said, “With four things : No one but a Muslim will enter Paradise. Do not make tawaf of the House in the nude. The Muslims and the idolators will not come together (for Hajj) after this year. If there is a covenant between anyone and the Prophet (SAW) then that will be valid till its expriy but if no period is stipulated then it will operate for four months.’
