Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Do not combine my name and my kunyah. I am Abu al-Qasim. Allah gives, and I distribute."
(Imam Ibn Hibban, may Allah have mercy on him, says:) This narration has been heard by Ibn ‘Ajlan from Makbari and from his father, both. Both narrators are trustworthy, and both chains of this narration are preserved.
