‘Abdullah bin Kinanah bin ‘Abbas bin Mirdas As-Sulami narrated that his father told him, from his father, that the Messenger of Allah (ﷺ) prayed for forgiveness for his nation one evening at ‘Arafat, and the response came:
“I have forgiven them, except for the wrongdoer, with whom I will settle the score in favor of the one whom he wronged.” He said: “O Lord, if You will, then grant Paradise to the one who is wronged, and forgive the wrongdoer.” No response came (that evening).The next day at Muzdalifah he repeated the supplication, and received a response to what he asked for. He (the narrator) said: “The Messenger of Allah (ﷺ) laughed,” or he said, “He smiled. Abu Bakr and ‘Umar said to him: ‘May my father and mother be ransomed for you, this is not a time when you usually laugh. What made you laugh, may Allah make your years filled with laughter?’ He said: ‘The enemy of Allah, Iblis, when he came to know that Allah answered my prayer and forgiven my nation, took some dust and started to sprinkle it on his head, uttering cries of woe and doom, and what I saw of his anguish made me laugh.’”
