Sayyiduna Abu Lubabah (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever does not recite the Qur'an melodiously has nothing to do with us." I said to Ibn Abi Mulaykah (may Allah have mercy on him): What if the voice is not beautiful? He said: Let him make his voice as beautiful as he can.
The chain of this hadith is disputed on Ibn Abi Mulaykah: it is narrated from him in these two ways, and it is also said: from him from Sayyiduna Ibn Abbas (may Allah be pleased with them both), and: from him from Sayyidah Aishah (may Allah be pleased with her), and otherwise.
