Sahih Muslim 2905 f
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".
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عُمَرَ بْنِ أَبَانَ، وَوَاصِلُ بْنُ عَبْدِ الأَعْلَى، وَأَحْمَدُ بْنُ عُمَرَ الْوَكِيعِيُّ،
 - وَاللَّفْظُ لاِبْنِ أَبَانَ - قَالُوا حَدَّثَنَا ابْنُ فُضَيْلٍ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ سَالِمَ بْنَ عَبْدِ اللَّهِ،
 بْنِ عُمَرَ يَقُولُ يَا أَهْلَ الْعِرَاقِ مَا أَسْأَلَكُمْ عَنِ الصَّغِيرَةِ وَأَرْكَبَكُمْ لِلْكَبِيرَةِ سَمِعْتُ أَبِي عَبْدَ
 اللَّهِ بْنَ عُمَرَ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم 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 عَزَّ وَجَلَّ
 لَهُ ‏{‏ وَقَتَلْتَ نَفْسًا فَنَجَّيْنَاكَ مِنَ الْغَمِّ وَفَتَنَّاكَ فُتُونًا‏}‏ قَالَ أَحْمَدُ بْنُ عُمَرَ فِي رِوَايَتِهِ عَنْ
 سَالِمٍ لَمْ يَقُلْ سَمِعْتُ ‏.‏
