عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((الْتَمِسُوهَا فِي الْعَشْرِ الْأَوَاخِرِ فِي تَاسِعَةٍ تَبْقَى، أَوْ خَامِسَةٍ تَبْقَى أَوْ سَابِعَةٍ تَبْقَى))
Narrated by Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Seek it in the last ten nights, when nine or five or seven nights remain.
