Ubaydullah bin Abi Yazid said: Abu Lubabah (may Allah be pleased with him) passed by us, so we followed him until he entered his house. We went in to him, and found him a man with a shabby house and a shabby appearance. I heard him say: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever does not recite the Qur'an melodiously is not one of us." I said to Ibn Abi Mulaykah: O Abu Muhammad! What if a man's voice is not beautiful, what should he do? He said: He should try to make it beautiful as much as he can.
