باب مَنْ أَشْرَكَ فِي عَمَلِهِ غَيْرَ اللَّهِ
Sahih Muslim 2986

Ibn Abbas reported Allah's Messenger (ﷺ) as saying:

If anyone wants to have his deeds widely publicised, Allah will publicise (his humiliation). And if anyone makes a hypocritical display (of his deeds) Allah will make a display of him.
حَدَّثَنَا عُمَرُ بْنُ حَفْصِ بْنِ غِيَاثٍ، حَدَّثَنِي أَبِي، عَنْ إِسْمَاعِيلَ بْنِ سُمَيْعٍ، عَنْ مُسْلِمٍ، الْبَطِينِ عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنْ سَمَّعَ سَمَّعَ اللَّهُ بِهِ وَمَنْ رَاءَى رَاءَى اللَّهُ بِهِ ‏"‏ ‏.‏
