`Sayyiduna Jarir (may Allah be pleased with him) says that I heard the Messenger of Allah (peace and blessings of Allah be upon him), he (peace be upon him) used to say: Whoever is deprived of gentleness is deprived of goodness.

Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) narrates from the Prophet (peace and blessings be upon him) that he said: Gentleness is not found in anything except that it beautifies it, and it is not removed from anything except that it makes it defective.
