Amrah bint Abd al-Rahman narrates from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "O Aishah! Allah Almighty is Gentle and loves gentleness. He gives for gentleness what He does not give for harshness, and what He does not give for anything else."
