ʿAbdullāh Ibn Masʿūd said: Whoever wishes to see the advice of Muḥammad (ṣallallāhu ʿalayhi wa-sallam) which has his seal upon it, then let him read the statement of Allāh the Exalted: "Say: Come! Read what your Lord has forbidden for you: that you should not associate with Him anything."[To His Statement:] "And verily this is My Straight Path" [Sūrah al-Anʿām 151-153] [Tirmidthī (no. 3072). And he said: "good but strange". Muḥammad Afīfī confirmed it in his checking of Kitāb al-Tawḥīd of Shaykh al Islām Muḥammad Ibn ʿAbd al Wahhāb.]
Shaykh ʿAbd al-Raḥmān Ibn Ḥasan Āl Ash-Shaykh said: This narration was narrated by Tirmidthī who declared it good, and Ibn Mundthir, and Ibn Abī Ḥātim, and al-Ṭabarānī, and their like. Some of them said: It's meaning is: Whoever wishes to see the advice which is as if it was written and sealed, and then it was not modified and it was not changed, then let him read: "Say: Come!" - to the end of the āyah. It is like the book, which was written, then sealed, then it was not added to, and it did not have anything deleted from it. For verily the Messenger of Allāh (ṣallallāhu ʿalayhi wa-sallam) did not advise except with the Book of Allāh, as he said in that which is related by Muslim: And verily I have left with you that which if you cling firmly to it, you shall not be misguided: the Book of Allāh… And indeed it is reported from ʿUbādah Ibnus Sāmit that the Messenger of Allāh (ṣallallāhu ʿalayhi wa-sallam) said: "Which one of you wants to buy from me these three āyāt?" Then he read His Statement: Say: Come! Recite what your Lord has forbidden for you… until he was exhausted from these three āyahs. Then he said: "And whoever completes these, then his reward is with Allāh, and whoever has something incomplete from this, then Allāh knows about it in this world, and he will be punished. And whoever is after him until the Hereafter, his affair is with Allāh. If He wishes, He will take him, and if He wishes, He will forgive him. It is related by Ibn Abī Ḥātim, and authenticated by al-Ḥākim, and Muḥammad Ibn Naṣr in Al-I'itsām. I say: because the Prophet (ṣallallāhu ʿalayhi wa-sallam) did not advise his Ummah except with what Allāh the Exalted advised them, upon his tongue, and in the Book which He revealed. "An Explanation for everything, and a Guidance, and a Mercy, and a Glad Tiding for the Muslims" [Sūrah al-Naḥl: 89]. And these āyahs are the advice of Allāh the Exalted and His Messenger (ṣallallāhu ʿalayhi wa-sallam) [Fat‘h al Majīd (1/23)].
