Allah’s Apostle (S) was the most eloquent speaker of all of Allah’s creation. His speech was sweet, comprehensive, and he had the most beautiful way with words. His words captured the hearts and souls. Even his enemies had to admit to this quality.
—Ibn al-Qayyim [d. 751H/1350CE]
(English Translation of Zad-ul Ma’ad fi Hadyi Khairi-l ‘Ibad 1/312))
Politeness is part of the attitude of the believers, and it is lowering the wing of humility to people, speaking gently, and not speaking harshly to them, which are among the best means of creating harmony
