صَحِيحُ مُسْلِمٍ
Sahih Muslim 131 b
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
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 .
This hadith has been narrated with another chain of transmitters with the addition of these words: 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.
