During the lifetime of Messenger of Allah ﷺ the moon was split into two parts; one part remained over the mountain, and the other part went beyond the mountain. On that, Messenger of Allah ﷺ said, "Witness this miracle."  

انْشَقَّ الْقَمَرُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فِرْقَتَيْنِ فِرْقَةً فَوْقَ الْجَبَلِ وَفِرْقَةً دُونَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ اشْهَدُوا  

[Machine] In the saying of Allah, the Exalted, "{The Hour has drawn near, and the moon has split.}" [Surah Al-Qamar 54:1], it is said that this occurred during the time of the Prophet ﷺ when the moon split into two halves: one half was on one side of the mountain and the other half was on the other side. The Prophet ﷺ then said, "O Allah, bear witness."  

فِي قَوْلِهِ ﷻ {اقْتَرَبَتِ السَّاعَةُ وَانْشَقَّ الْقَمَرُ} [القمر 1] قَالَ كَانَ ذَلِكَ عَلَى عَهْدِ النَّبِيِّ ﷺ انْشَقَّ الْقَمَرُ فِلْقَتَيْنِ فِلْقَةٌ مِنْ دُونِ الْجَبَلِ وَفِلْقَةٌ خَلْفَ الْجَبَلِ فَقَالَ النَّبِيُّ ﷺ «اللَّهُمَّ اشْهَدْ»  

[Machine] The moon split during the time of the Prophet Muhammad ﷺ into two halves; one half was above the mountain, and the other half was covered by the mountain. The Prophet Muhammad ﷺ said, "O Allah, bear witness."  

انْشَقَّ الْقَمَرُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ شِقَّتَيْنِ شِقَّةٌ فَوْقَ الْجَبَلِ وَشِقَّةٌ سَتَرَهَا الْجَبَلُ فَقَالَ رَسُولُ اللهِ ﷺ «اللهُمَّ اشْهَدْ»
