It is narrated from Hazrat Ata bin Abi Rabah that he says: When Hazrat Ali (may Allah be pleased with him) ibn Abi Talib would send out a military expedition, he would appoint a man over it and advise him. He would say: I advise you to fear Allah. You will surely meet Allah, and after Him, there is no end for you. He alone is the Owner of this world and the Hereafter, and you must certainly do those deeds which bring you closer to Allah, because whatever is with Allah is also the successor of the wealth of this world.
