صحيح البخاري

Narrated Anas:

A bedouin came to the Prophet (ﷺ) and said, "O Allah's Messenger! When will The Hour be established?" The Prophet (ﷺ) said, "Wailaka (Woe to you), What have you prepared for it?" The bedouin said, "I have not prepared anything for it, except that I love Allah and H is Apostle." The Prophet (ﷺ) said, "You will be with those whom you love." We (the companions of the Prophet (ﷺ) ) said, "And will we too be so? The Prophet (ﷺ) said, "Yes." So we became very glad on that day. In the meantime, a slave of Al-Mughira passed by, and he was of the same age as I was. The Prophet (ﷺ) said. "If this (slave) should live long, he will not reach the geriatric old age, but the Hour will be established."
