I asked ʿAbdullah bin ʿAmr bin Al-ʿAs to inform me of the worst thing the pagans had done to Allah's Apostle. He said: "While Messenger of Allah ﷺ was praying in the courtyard of the Kaʿba, ʿUqba bin Abi Mu'ait came and seized Messenger of Allah ﷺ by the shoulder and twisted his garment round his neck and throttled him severely. Abu Bakr came and seized ʿUqba's shoulder and threw him away from Allah's Apostle and said, "Would you kill a man because he says: 'My Lord is Allah,' and has come to you with clear Signs from your Lord?" (40.28) (Using translation from Bukhārī 4815)
حَدِّثْنِي بِأَشَدِّ شَيْءٍ صَنَعَهُ الْمُشْرِكُونَ بِرَسُولِ اللهِ ﷺ قَالَ أَقْبَلَ عُقْبَةُ بْنُ أَبِي مُعَيْطٍ وَرَسُولُ اللهِ ﷺ يُصَلِّي عِنْدَ الْكَعْبَةِ فَلَوَى ثَوْبَهُ فِي عُنُقِهِ فَخَنَقَهُ خَنْقًا شَدِيدًا فَأَقْبَلَ أَبُو بَكْرٍ ؓ فَأَخَذَ بِمَنْكِبَيْهِ فَدَفَعَهُ عَنْ رَسُولِ اللهِ ﷺ فَقَالَ أَتَقْتُلُونَ رَجُلًا أَنْ يَقُولَ رَبِّيَ اللهُ وَقَدْ جَاءَكُمْ بِالْبَيِّنَاتِ مِنْ رَبِّكُمْ؟
