عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”نِعْمَ الْقَوْمُ الْأَزْدُ طَيِّبَةٌ أَفْوَاهُهُمْ بَرَّةٌ أَيْمَانُهُمْ نَقِيَّةٌ قُلُوبُهُمْ“
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Banu Azd are the best people; their mouths, that is, their speech, is extremely excellent, they fulfill their vows, and their hearts are clean and pure (from malice, envy, and rancor, etc.).
