Hadith 17:594
Waki' narrated to us, from Hisham, from his father, who said: When the Prophet, peace and blessings of Allah be upon him, would hear an ugly name, he would change it to something better than it.
حدثنا وكيع عن هشام عن أبيه قال كان النبي صلى الله عليه وسلم إذا سمع الاسم القبيح حوله إلى ما هو أحسن منه
