وَلَوْ أَنَّ قُرْءَانًۭا سُيِّرَتْ بِهِ ٱلْجِبَالُ أَوْ قُطِّعَتْ بِهِ ٱلْأَرْضُ أَوْ كُلِّمَ بِهِ ٱلْمَوْتَىٰ ۗ بَل لِّلَّهِ ٱلْأَمْرُ جَمِيعًا ۗ أَفَلَمْ يَا۟يْـَٔسِ ٱلَّذِينَ ءَامَنُوٓا۟ أَن لَّوْ يَشَآءُ ٱللَّهُ لَهَدَى ٱلنَّاسَ جَمِيعًۭا ۗ وَلَا يَزَالُ ٱلَّذِينَ كَفَرُوا۟ تُصِيبُهُم بِمَا صَنَعُوا۟ قَارِعَةٌ أَوْ تَحُلُّ قَرِيبًۭا مِّن دَارِهِمْ حَتَّىٰ يَأْتِىَ وَعْدُ ٱللَّهِ ۚ إِنَّ ٱللَّهَ لَا يُخْلِفُ ٱلْمِيعَادَ
Had it been possible for a Lecture to cause the mountains to move, or the earth to be torn asunder, or the dead to speak, (this Qur'an would have done so). Nay, but Allah's is the whole command. Do not those who believe know that, had Allah willed, He could have guided all mankind? As for those who disbelieve, disaster ceaseth not to strike them because of what they do, or it dwelleth near their home until the threat of Allah come to pass. Lo! Allah faileth not to keep the tryst.
Surah Ar-Ra'd(13:31)
Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
The Statement of Allah the Exalted: "Glorified (and Exalted) is He (Allah) [above all that (evil) they associate with Him], Who took His slave (Muḥammad pbuh) for a Journey by Night from Al-Masjid-al-Ḥarām (at Makkah) to Al-Masjid-al-Aqsā (in Jerusalem)..." (V.17:1)
Narrated Abu Huraira:
Allah's Messenger (ﷺ) was presented with two cups one containing wine and the other milk on the night of his night journey at Jerusalem. He looked at it and took the milk. Gabriel said, "Thanks to Allah Who guided you to the Fitra (i.e. Islam); if you had taken the wine, your followers would have gone astray.
