Aisha (may Allah be pleased with her) narrates that the Prophet (peace and blessings of Allah be upon him) said: "Whoever is given his share with gentleness, he has been given his share of goodness in this world and the Hereafter. And whoever is deprived of his share of gentleness, he is deprived of his share of goodness in this world and the Hereafter." Hasan, narrated in Sharh al-Sunnah.
