"The Messenger of Allah [SAW] said to me: 'Ask the people to be quiet and listen.' Then he said: 'I do not want to see you after I am gone reverting to disbelievers, striking the necks of one another (killing one another).'" (Using translation from Nasāʾī 4132)
لِي رَسُولُ اللهِ ﷺ اسْتَنْصِتِ النَّاسَ ثُمَّ قَالَ عِنْدَ ذَلِكَ لَا أَعْرِفَنَّ بَعْدَمَا أَرَى تَرْجِعُونَ بَعْدِي كُفَّارًا يَضْرِبُ بَعْضُكُمْ رِقَابَ بَعْضٍ
