Narrated Anas: The people of Mecca asked the Prophet to show them a sign (miracle). So he showed them (the miracle) of the cleaving of the moon.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا يُونُسُ بْنُ مُحَمَّدٍ، حَدَّثَنَا شَيْبَانُ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ سَأَلَ أَهْلُ مَكَّةَ أَنْ يُرِيَهُمْ آيَةً فَأَرَاهُمُ انْشِقَاقَ الْقَمَرِ.
