700 folds and more as mentioned ( And Allah multiplies ˹the reward even more˺).
(The example of those who spend their wealth in the cause of Allah is that of a grain that sprouts into seven ears, each bearing one hundred grains. And Allah multiplies ˹the reward even more˺ to whoever He wills. For Allah is All-Bountiful, All-Knowing.) [Al-Baqara 2:261]
أن الله يضاعف الصدقة لصاحبها سبع مئة ضعف و زيادة على ذلك. ( وَاللَّهُ يُضَاعِفُ لِمَنْ يَشَاءُ ۗ)
مَثَلُ الَّذِينَ يُنْفِقُونَ أَمْوَالَهُمْ فِي سَبِيلِ اللَّهِ كَمَثَلِ حَبَّةٍ أَنْبَتَتْ سَبْعَ سَنَابِلَ فِي كُلِّ سُنْبُلَةٍ مِائَةُ حَبَّةٍ ۗ وَاللَّهُ يُضَاعِفُ لِمَنْ يَشَاءُ ۗ وَاللَّهُ وَاسِعٌ عَلِيمٌ) ]البقرة 2: 261
