A man came to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) to greet him with salam and told him that he was setting out on a journey. So Sayyiduna Ibn Umar (may Allah be pleased with them both) said to him: "Come, let me bid you farewell just as I heard the Messenger of Allah (peace and blessings be upon him) bidding farewell to one setting out on a journey." Then Abdullah (may Allah be pleased with him) said: "I entrust to Allah your trust, your religion and the final outcome of your deeds."
