وَعَنِ ابْنِ عَبَّاسٍ
أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ فِي الْمُعْتَكَفِ: «هُوَ يَعْتَكِفُ الذُّنُوبَ وَيُجْرَى لَهُ مِنَ الْحَسَنَاتِ كَعَامِلِ الْحَسَنَات كلهَا»
Ibn Abbas reported God’s messenger as saying about one who observes a period of private devotion in a mosque, “He turns away from sins and he is rewarded for good deeds like one who does all good deeds.”
