It is narrated from Sayyiduna Buraydah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) heard a man saying: 'Allahumma inni as'aluka bi-annaka Ahadun Samad, lam yalid wa lam yulad, wa lam yakun laka kufuwan ahad' (O Allah, I ask You by virtue of the fact that You are One, Self-Sufficient; You neither begot anyone nor were You begotten, and there is none equal to You). He (peace and blessings be upon him) said: "He has certainly asked Allah by His Greatest Name, or he said: His Most Great Name, by which, when He is called upon, He answers, and when He is asked, He gives." This is a supporting narration (shahid) for the previous hadith, whose chain is sahih on the condition of Imam Muslim.
