Narrated Urwa bin Az-Zubair:

I asked 'Abdullah bin 'Amr bin Al-'As to inform me of the worst thing the pagans had done to Allah's Apostle. He said: "While Allah's Apostle was praying in the courtyard of the ka'ba, 'Uqba bin Abi Mu'ait came and seized Allah's Apostle by the shoulder and twisted his garment round his neck and throttled him severely. Abu Bakr came and seized 'Uqba'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)

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنَا الأَوْزَاعِيُّ، قَالَ حَدَّثَنِي يَحْيَى بْنُ أَبِي كَثِيرٍ، قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ إِبْرَاهِيمَ التَّيْمِيُّ، قَالَ حَدَّثَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، قَالَ قُلْتُ لِعَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ أَخْبِرْنِي بِأَشَدِّ، مَا صَنَعَ الْمُشْرِكُونَ بِرَسُولِ اللَّهِ ﷺ قَالَ بَيْنَا رَسُولُ اللَّهِ ﷺ يُصَلِّي بِفِنَاءِ الْكَعْبَةِ، إِذْ أَقْبَلَ عُقْبَةُ بْنُ أَبِي مُعَيْطٍ، فَأَخَذَ بِمَنْكِبِ رَسُولِ اللَّهِ ﷺ وَلَوَى ثَوْبَهُ فِي عُنُقِهِ فَخَنَقَهُ خَنْقًا شَدِيدًا، فَأَقْبَلَ أَبُو بَكْرٍ فَأَخَذَ بِمَنْكِبِهِ، وَدَفَعَ عَنْ رَسُولِ اللَّهِ ﷺ وَقَالَ أَتَقْتُلُونَ رَجُلاً أَنْ يَقُولَ رَبِّيَ اللَّهُ وَقَدْ جَاءَكُمْ بِالْبَيِّنَاتِ مِنْ رَبِّكُمْ
