The best in Islam are those with the best character
I heard Abū al-Qāsim (the Prophet) ﷺ say, "The best of you in Islam are those with the best character, if they have a good ˹religious˺ understanding."
سَمِعْتُ أَبَا الْقَاسِمِ ﷺ يَقُولُ «خَيْرُكُمْ إِسْلَامًا أَحَاسِنُكُمْ أَخْلَاقًا إِذَا فَقِهُوا۔»
