Narrated Wathilah ibn al-Asqa:

Al-Arif ibn ad-Daylami said: We went to Wathilah ibn al-Asqa and said to him: Tell us a tradition which has not addition or omission. He became angry and replied: One of you recites when his copy of a Qur'an is hung up in his house, and he makes additions and omissions. We said: All we mean is a tradition you have heard from the Messenger of Allah ﷺ. He said: We went to the Prophet ﷺ about a friend of ours who deserved. Hell for murder. He said: Emancipate a slave on his behalf; Allah will set free from Hell a member of the body for every member of his.

حَدَّثَنَا عِيسَى بْنُ مُحَمَّدٍ الرَّمْلِيُّ، حَدَّثَنَا ضَمْرَةُ، عَنْ إِبْرَاهِيمَ بْنِ أَبِي عَبْلَةَ، عَنِ الْغَرِيفِ بْنِ الدَّيْلَمِيِّ، قَالَ أَتَيْنَا وَاثِلَةَ بْنَ الأَسْقَعِ فَقُلْنَا لَهُ حَدِّثْنَا حَدِيثًا، لَيْسَ فِيهِ زِيَادَةٌ وَلاَ نُقْصَانٌ فَغَضِبَ وَقَالَ إِنَّ أَحَدَكُمْ لَيَقْرَأُ وَمُصْحَفُهُ مُعَلَّقٌ فِي بَيْتِهِ فَيَزِيدُ وَيَنْقُصُ . قُلْنَا إِنَّمَا أَرَدْنَا حَدِيثًا سَمِعْتَهُ مِنَ النَّبِيِّ ﷺ . قَالَ أَتَيْنَا رَسُولَ اللَّهِ ﷺ فِي صَاحِبٍ لَنَا أَوْجَبَ - يَعْنِي - النَّارَ بِالْقَتْلِ فَقَالَ
" أَعْتِقُوا عَنْهُ يُعْتِقِ اللَّهُ بِكُلِّ عُضْوٍ مِنْهُ عُضْوًا مِنْهُ مِنَ النَّارِ " .
