Anas ibn Malik radiyallahuanhu reported: We were sitting with the Messenger of Allah, peace and blessings be upon him, and he said, “Coming upon you now is a man from the people of Paradise.” A man from the Ansar came whose beard was disheveled by the water of ablution and he was carrying both of his shoes with his left hand. The next day the Prophet ﷺ repeated the same words, and the man came in the same condition. The third day the Prophet ﷺ repeated the same again, and the man came in the same condition. When the Prophet ﷺ stood up to leave, Abdullah ibn Amr radiyallahuanhu followed the man and he said, “I am in a dispute with my father and I have sworn not to enter my home for three days. May I stay with you?” The man said yes.
Abdullah stayed three nights with the man but he never saw him praying at night. Whenever he went to bed, he would remember Allah and rest until he woke up for morning prayer. Abdullah said that he never heard anything but good words from his mouth. When three nights had passed and he did not see anything special about his actions, Abdullah asked him, “O servant of Allah, I have not been in dispute with my father nor have I cut relations with him. I heard the Prophet ﷺ say three times that a man from the people of Paradise was coming to us and then you came. I thought I should stay with you to see what you are doing that I should follow, but I did not see you do anything special. Why did the Prophet ﷺ speak highly of you?” The man said, “I am as you have seen.” When Abdullah was about to leave, the man said, “I am as you have seen, except that I do not find dishonesty in my soul towards the Muslims and I do not envy anyone because of the good that Allah has given them.” Abdullah said, “This is what you have achieved and it is something we have not accomplished.”
