عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ مَنْ أُتِيَ إِلَيْهِ مَعْرُوفٌ فَلْيُكَافِئْ بِهِ وَمَنْ لَمْ يَسْتَطِعْ فَلْيَذْكُرْهُ فَمَنْ ذَكَرَهُ فَقَدْ شَكَرَهُ وَمَنْ تَشَبَّعَ بِمَا لَمْ يَنَلْ فَهُوَ كَلَابِسِ ثَوْبَيْ زُورٍ
It is narrated from Sayyida Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: Whoever is done a favor, let him repay it; if he is unable to repay it, then let him mention it. Thus, whoever mentions it has expressed gratitude for it, and whoever displays a blessing which he does not possess is like a person who wears two garments of falsehood.
