وَعَنْ أُسَامَةَ بْنِ زَيْدٍ رَضِيَ اَللَّهُ عَنْهُمَا قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ: مَنْ صُنِعَ إِلَيْهِ مَعْرُوفٌ، فَقَالَ لِفَاعِلِهِ: جَزَاكِ اَللَّهُ خَيْراً، فَقَدْ أَبْلَغَ فِي اَلثَّنَاءِ . رَوَاهُ التِّرْمِذِيُّ وَقَالَ حَدِيثٌ حَسَن صَحِيح .
Usamah bin Zaid (May Allah be pleased with them) reported: The Messenger of Allah (ﷺ) said, "He who is favoured by another and says to his benefactor: `Jazak-Allah khairan (may Allah reward you well)' indeed praised (the benefactor) satisfactorily.'' [At-Tirmidhi].
