عَنْ عَبْدِ اللَّهِ بْنِ أُنَيْسٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ لَهُمْ وَسَأَلُوهُ عَنْ لَيْلَةٍ يَتَرَاءَوْنَهَا فِي رَمَضَانَ، قَالَ: ((لَيْلَةُ ثَلَاثٍ وَعِشْرِينَ))
Narrated by Sayyiduna Abdullah bin Unais (may Allah be pleased with him): When people asked the Noble Prophet (peace and blessings be upon him) about the Night of Qadr in Ramadan, so that they could seek it, he (peace and blessings be upon him) said: It is the twenty-third night.
