Narrated Ibn Mas'ud, may Allah be pleased with him:

"We were with the Messenger of Allah ﷺ in Mina, when the moon was cleft asunder into two parts. Part of it was behind the mountain, and part of it before it. The Messenger of Allah ﷺ said to us: 'Bear witness' meaning: The house has drawn near, and the moon has been cleft asunder (54:1)."

حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ، أَخْبَرَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ أَبِي مَعْمَرٍ، عَنِ ابْنِ مَسْعُودٍ، رَضِيَ اللَّهُ عَنْهُ قَالَ بَيْنَمَا نَحْنُ مَعَ رَسُولِ اللَّهِ ﷺ بِمِنًى فَانْشَقَّ الْقَمَرُ فِلْقَتَيْنِ فِلْقَةٌ مِنْ وَرَاءِ الْجَبَلِ وَفِلْقَةٌ دُونَهُ فَقَالَ لَنَا رَسُولُ اللَّهِ ﷺ " اشْهَدُوا " . يَعْنِي : (اقتَرَبَتِ السَّاعَةُ وَانْشَقَّ الْقَمَرُ ) قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
