"The people of Makkah asked the Prophet ﷺ for a sign, so the moon was cleft asunder in Makkah two times (meaning two parts), so the following was revealed: 'The Hour has drawn near, and the moon has been cleft asunder, up to his saying: 'Magic, Mustamir (54:1 & 2)' meaning 'Going away.'" (Using translation from Tirmidhī 3286)
عَنْ أَنَسٍ سَأَلَ أَهْلُ مَكَّةَ النَّبِيَّ ﷺ آيَةً فَانْشَقَّ الْقَمَرُ بِمَكَّةَ مَرَّتَيْنِ فَقَالَ {اقْتَرَبَتِ السَّاعَةُ وَانْشَقَّ الْقَمَرُ وَإِنْ يَرَوْا آيَةً يُعْرِضُوا وَيَقُولُوا سِحْرٌ مُسْتَمِرٌّ} [القمر 2]
