Khabbab bin Arat relates: “We complained to Allah’s Messenger ﷺ of our increasing persecution by non-believers of Makkah. He was then reclining in the shade of Ka‘aba, having made a pillow of his sheet. We requested: ‘Why do you not pray for heavenly help for us? Why do you not request for Allah’s help for us?’ He answered: ‘From among those who have gone before you, a man would be caught and held in a pit dug for him in the earth and he would then be sawn in two with a saw placed over his head, or his flesh would be combed away from his bones with iron combs; but none of this would wean him away from his faith. Allah will surely help Islam complete his mission, till a rider will proceed from San’aa to Hadharmaut, fearing nothing save Allah and the danger of the wolf concerning his sheep. But you appear to be in too much of a hurry’.”
(Bukhari)
Allah would surely help Islam complete its mission. Then there would be no rule but the rule of Allah, and all the affairs of the world would be run according to the Qur’ān and Sunnah. The society would be completely rid of all sorts of loot and corruption. The Messenger of Allah ﷺ said with a ring of confidence in his tone that the day would witness total peace. The image of a rider proceeding from San’aa to Hadharmaut is symbolic of the situation when total peace would prevail on earth.
