Masrūq reported: I was reclining in the house of ‘Ā’ishah when she said: "O Abu ‘Ā’ishah, there are three things, whoever speaks of one of them has fabricated a tremendous lie against Allah; whoever claims that Muhammad (may Allah's peace and blessings be upon him) saw his Lord, then he has fabricated a tremendous lie against Allah." I was reclining, so I sat up an said: "O Mother of the Believers, give me enough time and do not be hasty! Did not Allah, Glorified and Exalted, say: {And truly he saw him on the clear horizon} [Sūrat At-Takwīr: 23] and: {He saw Him in another descent.} [Sūrat An-Najm: 13]?" She said: "I am the first of this Ummah who asked the Messenger of Allah (may Allah's peace and blessings be upon him) about it; and he said: ‘Verily it is Jibrīl. I have never seen him in his original form in which he was created except on those two occasions (to which these verses refer); I saw him descending from the heaven and filling (the space) from the sky to the earth with the greatness of his bodily structure.’ Have you not heard that Allah says: {Eyes comprehend Him not, but He comprehends (all) vision. and He is Subtle, and All-Aware} [Sūrat al-An‘ām: 103]? Have you not heard that Allah says: {And it is not for any human being that Allah should speak to him except by revelation or from behind a partition or that He sends a messenger to reveal, by His permission, what He wills. Indeed, He is Most High and Wise.} [Sūrat Ash-Shūra: 51]. The one who presumes that the Messenger of Allah (may Allah's peace be upon him) concealed anything from the Book of Allah has fabricated the greatest lie against Allah. Allah says: {O Messenger, announce that which has been revealed to you from your Lord, and if you do not, then you have not conveyed His message} [Sūrat al-Mā’idah: 67]. The one who presumes that he would foretell what will happen tomorrow has fabricated the greatest lie against Allah. Allah, the Almighty says: {Say: None in the heavens and earth knows the unseen except Allah.} [Sūrat An-Naml: 65]"
Authentic hadith - Narrated by Bukhari & Muslim

The venerated Tābi‘i Masrūq was reclining in the house of the Mother of the Believers ‘Ā’ishah (may Allah be pleased with her). She told him: "There are three things, and the one who speaks of one of them has fabricated a tremendous lie against Allah." He asked her: "What are they?" She answered: 1. Whoever claims that Muhammad (may Allah's peace and blessings be upon him) saw his Lord has fabricated a tremendous lie. Masrūq was reclining, but then he sat upright an wondered: "How can you say that while Allah, the Exalted, said: {And truly he saw him on the clear horizon} [Sūrat At-Takwīr: 23] and: {He saw Him in another descent...} [Sūrat An-Najm: 13]?" She told him that she was the first ever to ask the Messenger of Allah (may Allah's peace and blessings be upon him) specifically about these two verses. he told her that it was Jibrīl (peace be upon him) whom he saw and that he has not seen him in his original form upon which Allah, the Exalted, created him except in those two instants; once on earth towards the direction of the sunrise, where everything appears in its most vivid form, and once in Paradise. He saw him descending from the heavens, filling the space between the heaven and the earth with his magnificent body. Then she cited two Qur’anic verses proving that the Prophet (may Allah's peace and blessings be upon him) has not seen his Lord. Allah says: {Eyes comprehend Him not, but He comprehends (all) vision, and He is Subtle and All-Aware.} [Sūrat al-An‘ām: 103]? And His saying: {And it is not for any human being that Allah should speak to him except by revelation or from behind a partition or that He sends a messenger to reveal, by His permission, what He wills. Indeed, He is Most High and Wise.} [Sūrat Ash-Shūra: 51] 2. Whoever claims that the Messenger of Allah (may Allah's peace and blessings be upon him) concealed anything from the Book of Allah has fabricated a tremendous lie against Allah. Allah said: {O Messenger, announce that which has been revealed to you from your Lord, and if you do not, then you have not conveyed His message.} [Sūrat al-Mā’idah: 67] 3. Whoever claims that the Messenger of Allah (may Allah's peace and blessings be upon him) could foretell the future on his own without revelation from Allah, the Exalted, has fabricated a tremendous lie against Allah. Allah says: {Say: None in the heavens and earth knows the unseen except Allah.} [Sūrat An-Naml: 65]
