Mujahid (may Allah have mercy on him) said: A man and I set out for jihad, and Abdullah bin Umar (may Allah be pleased with them both) saw us off. When he was about to part from us, he said: What the two of you have offered (in this path) pleases me, but I heard the Messenger of Allah (peace and blessings be upon him) say: "When something is entrusted to Allah, He protects it. And I entrust to Allah the religion of you both, your trust, and the final outcomes of your deeds."
