"...And the moon has been cleft asunder (the people of Makkah requested Prophet Muḥammad pbuh to show them a miracle, so he showed them the splitting of the moon). And if they see a sign, they turn away..." (V.54:1,2)
حَدَّثَنَا عَلِيٌّ، حَدَّثَنَا سُفْيَانُ، أَخْبَرَنَا ابْنُ أَبِي نَجِيحٍ، عَنْ مُجَاهِدٍ، عَنْ أَبِي مَعْمَرٍ، عَنْ عَبْدِ اللَّهِ، قَالَ انْشَقَّ الْقَمَرُ وَنَحْنُ مَعَ النَّبِيِّ صلى الله عليه وسلم فَصَارَ فِرْقَتَيْنِ، فَقَالَ لَنَا " اشْهَدُوا، اشْهَدُوا ".
Narrated `Abdullah: The moon was cleft asunder while we were in the company of the Prophet, and it became two parts. The Prophet (ﷺ) said, Witness, witness (this miracle).
