It is narrated from Sayyida Umm Darda’ (may Allah be pleased with her) that whenever Sayyiduna Abu Darda’ (may Allah be pleased with him) spoke, he would smile. I said to him:“Do not smile so much, lest people start calling you foolish.”He replied:“Whenever I saw or heard the Messenger of Allah (peace and blessings be upon him) speak, he would speak while smiling.”
