Sahih Muslim 2800c
انْشَقَّ الْقَمَرُ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فِلْقَتَيْنِ فَسَتَرَ الْجَبَلُ فِلْقَةً وَكَانَتْ فِلْقَةٌ فَوْقَ الْجَبَلِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " اللَّهُمَّ اشْهَدْ "
‘Abdullāh ibn Mas‘ūd (may Allah be pleased with him) reported that during the Prophet's lifetime, the moon split into two halves. The mountain covered one half, and the other half was above the mountain. The Messenger of Allah (may Allah’s peace and blessings be upon him) said: "O Allah, bear witness to this!"
During the time of the Messenger of Allah (may Allah’s peace and blessings be upon him), the moon split into two separate pieces each piece in a place. Thereupon, the Messenger of Allah (may Allah’s peace and blessings be upon him) said: "O Allah, bear witness to this!" i.e. O Allah, bear witness to the fact that I showed them a sign and a miracle that proves my prophet-hood.
Explanation in Arabic
انشق القمر في زمان رسول الله صلى الله عليه وسلم قطعتين متفارقتين كل قطعة في مكان، فقال رسول الله صلى الله عليه وسلم : «اللهم اشهد» أي: اللهم اشهد عليهم أنني قد أريتهم الدليلَ على صدق نبوتي.
انشقاق القمر من الآيات التي تدل على صدق النبي -صلى الله عليه وسلم-؛ لأنه أمر خارج عن الأمور الأرضية.
انْشَقَّ الْقَمَرُ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فِرْقَتَيْنِ، فِرْقَةً فَوْقَ الْجَبَلِ وَفِرْقَةً دُونَهُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " اشْهَدُوا "
