The Messenger of Allah ﷺ said: (The reward of) prayer, fasting and remembrance of Allah is enhanced seven hundred times over (the reward of) spending in Allah's path.
قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الصَّلاَةَ وَالصِّيَامَ وَالذِّكْرَ تُضَاعَفُ عَلَى النَّفَقَةِ فِي سَبِيلِ اللَّهِ بِسَبْعِمِائَةِ ضِعْفٍ
