“Those who spend their wealth in the way of God can be compared to a grain of corn which brings forth seven ears, each bearing a hundred grains. God [in accordance with His wisdom] provides in abundance [in this manner] to whom He wills; And [in reality] God is munificent and all-knowing. (2:261)
Imam Amin Ahsan Islahi writes:
This is a parable which depicts the manifold increase in the reward for spending wealth in the way of God. It is said that just as seven ears sprout from a corn and each ear will have a hundred grains, similarly the reward of a deed given to a person can be up to seven hundred times. Some Hadith narratives also explain this theme. It is reported that the Prophet (sws) said that the reward of a good deed ranges from ten times to seven hundred times. This variation obviously depends on the nature of the deed, the time in which it is done and the internal and external circumstances of those who do the deed. If a good deed is done in difficult circumstances and with straitened resources, it will earn more reward and if a good deed is done in times of ease and with ample resources, its reward will be relatively less. The feelings of the people who do the deed also count. A good deed may be done with complete willingness of heart and enthusiasm and it may also be done half-heartedly and under compulsion. Obviously both would earn different reward. The verse depicts the maximum reward and it is said: “God provides in abundance [in this manner] to whom He wills.” This is a reference to the principle we have alluded to. Allah’s will is never against justice and wisdom. Hence this manifold reward is willed by Him only in favour of those who prove themselves worthy in accordance with the principle set for them.
This is further explained by saying that if this spending is done to please God and to discipline the soul, then this is the example of the person who plants an orchard not on land which is washed away by floods but on such high and even ground where the climate is also favourable so that if there is rain it bears double the fruit and if there is no rain, a light drizzle is sufficient to bear fruit because of conducive land and climatic conditions:
وَمَثَلُ الَّذِينَ يُنفِقُونَ أَمْوَالَهُمُ ابْتِغَاء مَرْضَاتِ اللّهِ وَتَثْبِيتًا مِّنْ أَنفُسِهِمْ كَمَثَلِ جَنَّةٍ بِرَبْوَةٍ أَصَابَهَا وَابِلٌ فَآتَتْ أُكُلَهَا ضِعْفَيْنِ فَإِن لَّمْ يُصِبْهَا وَابِلٌ فَطَلٌّ وَاللّهُ بِمَا تَعْمَلُونَ بَصِيرٌ (2: 265)
And those who spend their wealth to please God and to firmly attach their own souls [to the truth] are like an orchard which is on a high and level ground: if a heavy shower falls upon it, it yields up twice its normal produce; and even if a heavy shower does not fall on it, a drizzle is enough [to produce fruit. Keep this example in mind] and [rest assured that] God knows whatever you do. (2:265)“…
