“The Messenger of Allah (ṣ) said in a sermon, ‘Should I not inform you about the best of creation in this world and the Hereafter? [It is] the forgiveness offered to one who wrongs you, the good that is done to one who does you evil, and giving one who deprives you.’ And the Messenger of Allah (ṣ) said, ‘In mutual hatred there is severance. I do not mean the severing of hair [through shaving]; rather, I mean the severance of faith.’”
