حَدَّثَنَا عَلِيُّ بْنُ عَاصِمٍ عَنْ دَاوُدَ بْنِ أَبِي هِنْدٍ عَنْ عِكْرِمَةَ عَنِ ابْنِ عَبَّاسٍ أَنَّ رَجُلًا مِنْ الْأَنْصَارِ ارْتَدَّ عَنْ الْإِسْلَامِ وَلَحِقَ بِالْمُشْرِكِينَ فَأَنْزَلَ اللَّهُ تَعَالَى كَيْفَ يَهْدِي اللَّهُ قَوْمًا كَفَرُوا بَعْدَ إِيمَانِهِمْ إِلَى آخِرِ الْآيَةِ فَبَعَثَ بِهَا قَوْمُهُ فَرَجَعَ تَائِبًا فَقَبِلَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ذَلِكَ مِنْهُ وَخَلَّى عَنْهُ
مسند امام احمد بن حنبل · Hadith 2218
It was narrated from Ibn 'Abbas (RA) that a man from among the Ansar apostatised from Islam and joined the mushrikeen, then Allah revealed the verse: "How shall Allah guide a people who disbelieved after their Belief and after they bore witness that the Messenger (Muhammad (PBUH)) is true and after clear roofs had come unto them? And Allah guides not the people who are Zalimoon (polytheists and wrongdoers)" [A1 'Imran 3:86], His people sent word of that to him; he came back repenting and the Prophet (PBUH) accepted that from him and let him off.
