‘Abbas b. Mirdas said that Allah's Messenger ﷺ prayed for pardon for his people on the late evening of ‘Arafa and received the reply, “I have forgiven them all but acts of oppression, for I shall exact recompense for him who is wronged from his oppressor.” He said, “O my Lord, if Thou wilt Thou mayest give the oppressed some of paradise and forgive the oppressor,” but he did not receive a reply that evening. So he repeated the supplication at al-Muzdalifa in the morning and was given an answer to what he asked, whereupon he laughed (or he said that he smiled). Abu Bakr and ‘Umar then said to him, “You for whom we would give our fathers and mothers as ransom, what has made you laugh, for this is not a time at which you have been accustomed to laugh ? May Allah give you cause for laughter all your life !” He replied, “When Allah’s enemy, Iblls, knew that Allah who is great and glorious had answered my supplication and forgiven my people, he took some earth and began to throw it on his head crying out ‘Woe and destruction.’ The sight of his distress made me laugh.” Ibn Majah transmitted it, and Baihaqi transmitted something similar in Kitab al-ba‘th wan-nushur.
