It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him), he says: I was present in the house of the Messenger of Allah (peace and blessings be upon him) with him, when a man came and said: O Messenger of Allah! When will the Hour (Day of Judgment) come? The Prophet (peace and blessings be upon him) asked: It will certainly be established, but what preparation have you made for it? He said: By Allah! I have not done many deeds for the Day of Judgment, but I do love Allah and His Messenger. The Prophet (peace and blessings be upon him) said: You will be with those whom you love, and you will get what you hope for. After this, the Messenger of Allah (peace and blessings be upon him) stood up for prayer, and when he finished the prayer, he asked: Where is the man who asked about the Hour? So he was brought, and the Messenger of Allah (peace and blessings be upon him) looked towards the house, and his gaze fell upon a boy from the family of Banu Daws of Sayyiduna Abu Hurairah (may Allah be pleased with him), whose name was Sa’d bin Malik (may Allah be pleased with him). The Prophet (peace and blessings be upon him) said: If this boy lives, the Hour will come before he reaches old age. Hasan says: Sayyiduna Anas (may Allah be pleased with him) told me that the young man was his contemporary in those days.
