Yahya related to me from Malik from Ata ibn Abi Muslim that
Abdullah al-Khurasani said, "The Messenger of Allah, may Allah bless
him and grant him peace, said, 'Shake hands and rancour will
disappear. Give presents to each other and love each other and enmity
will disappear.' "
Muwatta Malik Book 47, Hadith 16
