PUTTING THINGS RIGHT H H 198 "O believers, recite this verse: 'Believers, look after your own souls, he who goes astray cannot harm you if you are guided. You shall all return to Allah, and He will inform you of what you have done.' 5:105 Koran I (Abu Bakr) heard the Prophet, praise and peace be upon him, say: 'When the people see a wrongdoer committing a wrong and do not seize his hand to restrain him, it is most likely that Allah would afflict them both with His punishment.'" R 198 Abu Daud, Tirmidhi and Nisai with a chain up to Abu Bakr Siddique who related this.
197- الرابع عشر : عن أَبي بكر الصديق رضي الله عنه ، قَالَ : يَا أيّها النَّاس ، إنّكم لتَقرؤُون هذِهِ الآية : ( يَا أَيُّهَا الَّذِينَ آمَنُوا عَلَيْكُمْ أَنْفُسَكُمْ لا يَضُرُّكُمْ مَنْ ضَلَّ إِذَا اهْتَدَيْتُمْ ) [ المائدة : 105 ] وإني سمعت رَسُول الله صلى الله عليه وآله وسلم ، يقول : "إنَّ النَّاسَ إِذَا رَأَوُا الظَّالِمَ فَلَمْ يأخُذُوا عَلَى يَدَيْهِ أوشَكَ أنْ يَعُمَّهُمُ اللهُ بِعِقَابٍ مِنْهُ" رواه أَبُو داود والترمذي والنسائي بأسانيد صحيحة .
