عن سهل بن سعد قال قال رسول الله صلى الله عليه وسلم لو كانت الدنيا تعدل عند الله جناح بعوضة ما سقى كافرا من شربة ماء (سنن الترمذي #2320)

Hazrat Sahl bin Sa’d (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “If the dunya was equal to the wing of a mosquito in the sight of Allah Ta‘ala, then Allah Ta‘ala would not have given a kaafir a sip of water to drink.”
