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. (Using translation from Abū Dāʾūd 2498)
قَالَ رَسُولُ اللَّهِ ﷺ «إِنَّ الصَّلَاةَ وَالصِّيَامَ وَالذِّكْرَ يُضَاعَفُ عَلَى النَّفَقَةِ فِي سَبِيلِ اللَّهِ بِسَبْعِ مِائَةِ ضِعْفٍ»
