Sahih Muslim 131
Sahih Muslim · Book 1: The Book of Faith · If a person thinks of doing a good deed it will be recorded for him, and if he thinks of doing a bad deed it will not be recorded for him
This hadith has been narrated with another chain of transmitters with the addition of these words:
وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى ، حَدَّثَنَا جَعْفَرُ بْنُ سُلَيْمَانَ ، عَنِ الْجَعْدِ أَبِي عُثْمَانَ ، فِي هَذَا الإِسْنَادِ بِمَعْنَى حَدِيثِ عَبْدِ الْوَارِثِ . وَزَادَ " وَمَحَاهَا اللَّهُ وَلاَ يَهْلِكُ عَلَى اللَّهِ إِلاَّ هَالِكٌ " .
Allah would even wipe out (the evil committed by a man) and Allah does not put to destruction anyone except he who is doomed to destruction.
