صحيح مسلم

Ibn Fudail reported on the authority of his father that he heard Salim b. `Abdullah b. `Umar as saying: O people of Iraq, how strange it is that you ask about the minor sins but commit major sins? I heard from my father `Abdullah b. `Umar, narrating that he heard Allah's Messenger (ﷺ) as saying while pointing his hand towards the east: Verily, the turmoil would come from this side, from where appear the horns of Satan and you would strike the necks of one another; and Moses killed a person from among the people of Pharaoh unintentionally and Allah, the Exalted and Glorious, said: "You killed a person but We relieved you from the grief and tried you with (many a) trial" (xx. 40). Ahmad b. `Umar reported this hadith from Salim, but he did not make a mention of the words: "I heard".
