Sahih al-Bukhari, Volume 6, Book 60, Hadith 339 (USC-MSA) ⓘ
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 Messenger was praying in the courtyard of the Ka`ba, `Uqba bin Abi Mu'ait came and seized Allah's Messenger 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 صلى الله عليه وسلم قَالَ بَيْنَا رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي بِفِنَاءِ الْكَعْبَةِ، إِذْ أَقْبَلَ عُقْبَةُ بْنُ أَبِي مُعَيْطٍ، فَأَخَذَ بِمَنْكِبِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَلَوَى ثَوْبَهُ فِي عُنُقِهِ فَخَنَقَهُ خَنْقًا شَدِيدًا، فَأَقْبَلَ أَبُو بَكْرٍ فَأَخَذَ بِمَنْكِبِهِ، وَدَفَعَ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم وَقَالَ {أَتَقْتُلُونَ رَجُلاً أَنْ يَقُولَ رَبِّيَ اللَّهُ وَقَدْ جَاءَكُمْ بِالْبَيِّنَاتِ مِنْ رَبِّكُمْ}
