Sayyiduna Ali (may Allah be pleased with him) was asked: With what were you sent? He replied: With four things; that only a believing soul can enter Paradise, no naked person will perform Tawaf of the House of Allah, after this year Muslims and polytheists will not perform Hajj together, and whoever has a treaty, his treaty will remain until its term, and whoever has no treaty, he has a respite of four months.
