وَإِذْ قَالَ ٱللَّهُ يَٰعِيسَى ٱبْنَ مَرْيَمَ ءَأَنتَ قُلْتَ لِلنَّاسِ ٱتَّخِذُونِى وَأُمِّىَ إِلَٰهَيْنِ مِن دُونِ ٱللَّهِ ۖ قَالَ سُبْحَٰنَكَ مَا يَكُونُ لِىٓ أَنْ أَقُولَ مَا لَيْسَ لِى بِحَقٍّ ۚ إِن كُنتُ قُلْتُهُۥ فَقَدْ عَلِمْتَهُۥ ۚ تَعْلَمُ مَا فِى نَفْسِى وَلَآ أَعْلَمُ مَا فِى نَفْسِكَ ۚ إِنَّكَ أَنتَ عَلَّٰمُ ٱلْغُيُوبِ
And when Allah saith: O Jesus, son of Mary! Didst thou say unto mankind: Take me and my mother for two gods beside Allah? he saith: Be glorified! It was not mine to utter that to which I had no right. If I used to say it, then Thou knewest it. Thou knowest what is in my mind, and I know not what is in Thy Mind. Lo! Thou, only Thou, art the Knower of Things Hidden?
Surah Al-Maaida(5:116)
Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
"And when We have recited it to you [O Muḥammad PBUH through Jibril (Gabriel) a.s.], then follow its (the Qur'an's) recital." (V.75:18)
Narrated Ibn `Abbas:
(as regards) Allah's Statement: "Move not your tongue concerning (the Qur'an) to make haste therewith." (75.16) When Gabriel revealed the Divine Inspiration in Allah's Messenger (ﷺ) , he (Allah's Messenger (ﷺ)) moved his tongue and lips, and that state used to be very hard for him, and that movement indicated that revelation was taking place. So Allah revealed in Surat Al-Qiyama which begins: 'I do swear by the Day of Resurrection...' (75) the Verses:-- 'Move not your tongue concerning (the Qur'an) to make haste therewith. It is for Us to collect it (Qur'an) in your mind, and give you the ability to recite it by heart. (75.16-17) Ibn `Abbas added: It is for Us to collect it (Qur'an) (in your mind), and give you the ability to recite it by heart means, "When We reveal it, listen. Then it is for Us to explain it," means, 'It is for us to explain it through your tongue.' So whenever Gabriel came to Allah's Messenger (ﷺ) ' he would keep quiet (and listen), and when the Angel left, the Prophet (ﷺ) would recite that revelation as Allah promised him.
