Concise Quran Commentary
The example of the reward of the believers who spend their wealth in Allah’s path is like that of a grain that is planted by a farmer in fertile ground. This grain then produces seven spikes, each carrying a hundred grains. Allah multiplies the reward for whomever of His servants He wishes and gives them their reward without account. Allah is Bountiful and Giving and He knows who deserves to have their reward multiplied.
