O people of Iraq, how strange it is that you ask about the minor sins but commit major sins? I heard from my father ʿAbdullah b. ʿUmar, narrating that he heard Messenger of Allah 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. ʿUmar reported this hadith from Salim, but he did not make a mention of the words: "I heard".  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ الْفِتْنَةَ تَجِيءُ مِنْ هَا هُنَا وَأَوْمَأَ بِيَدِهِ نَحْوَ الْمَشْرِقِ مِنْ حَيْثُ يَطْلُعُ قَرْنَا الشَّيْطَانِ وَأَنْتُمْ يَضْرِبُ بَعْضُكُمْ رِقَابَ بَعْضٍ وَإِنَّمَا قَتَلَ مُوسَى الَّذِي قَتَلَ مِنْ آلِ فِرْعَوْنَ خَطَأً فَقَالَ اللَّهُ ﷻ لَهُ { وَقَتَلْتَ نَفْسًا فَنَجَّيْنَاكَ مِنَ الْغَمِّ وَفَتَنَّاكَ فُتُونًا} قَالَ أَحْمَدُ بْنُ عُمَرَ فِي رِوَايَتِهِ عَنْ سَالِمٍ لَمْ يَقُلْ سَمِعْتُ
