Narrated `Abdullah bin Mas`ud:
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ ، حَدَّثَنَا شُعْبَةُ ، عَنْ عَمْرِو بْنِ مُرَّةَ ، عَنْ أَبِي وَائِلٍ ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ قُلْتُ أَنْتَ سَمِعْتَ هَذَا مِنْ عَبْدِ اللَّهِ قَالَ نَعَمْ، وَرَفَعَهُ. قَالَ " لاَ أَحَدَ أَغْيَرُ مِنَ اللَّهِ، فَلِذَلِكَ حَرَّمَ الْفَوَاحِشَ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ، وَلاَ أَحَدَ أَحَبُّ إِلَيْهِ الْمِدْحَةُ مِنَ اللَّهِ، فَلِذَلِكَ مَدَحَ نَفْسَهُ " .
Allah's Messenger (ﷺ) said, "None has more sense of ghaira than Allah, and for this He has forbidden shameful sins whether committed openly or secretly, and none loves to be praised more than Allah does, and this is why He Praises Himself."
