762. Shu'aib bin Abi Hamzah said: "Ibn Al-Munkadir, and Ibn Abī Farwah, and other among the Fuqahā' of Al-Madinah told me: 'When you say that' — meaning: 'Wa ana awwalul-muslimīn (And I am the first to submit myself)' — then you should say (instead): 'Wa ana minal-muslimīn (And I am of those who submit myself).'" (Sahih)
