عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((خَرَجْتُ حِينَ بَزَغَ الْقَمَرُ، كَأَنَّهُ فِلْقُ جَفْنَةٍ))، فَقَالَ: ((اللَّيْلَةَ لَيْلَةُ الْقَدْرِ))
It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: I went out at a time when the moon was rising, and it looked like half a tray. Then the Prophet (peace and blessings be upon him) said: Tonight is the Night of Qadr.
