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