The Messenger of Allah ﷺ said concerning the person observing I’tikaf. “He is refraining from sin and he will be given a reward like that of one who does all kinds of good deeds.”  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ فِي الْمُعْتَكِفِ هُوَ يَعْكِفُ الذُّنُوبَ وَيُجْرَى لَهُ مِنَ الْحَسَنَاتِ كَعَامِلِ الْحَسَنَاتِ كُلِّهَا
