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 اللهِ ﷺ إِنَّ الصَّلَاةَ وَالصِّيَامَ وَالذِّكْرَ تُضَاعَفُ عَلَى النَّفَقَةِ فِي سَبِيلِ اللهِ بِسَبْعِمِائَةِ ضِعْفٍ
