Striving in the Cause of God
[2:243] Have you noted those who fled their homes – though they were in the thousands – fearing death? GOD said to them, “Die,” then revived them. GOD showers His grace upon the people, but most people are unappreciative.
[2:244] You shall fight in the cause of GOD, and know that GOD is Hearer, Knower.
[2:245] Who would lend GOD a loan of righteousness, to have it repaid to them multiplied manifold? GOD is the One who provides and withholds, and to Him you will be returned.
In 2:243 it is interesting that the people feared death and therefore didn’t fight even though God is the one who controls life and death. This tells me that the only thing we control is what we choose to fear.
[3:156] O you who believe, do not be like those who disbelieved and said of their kinsmen who traveled or mobilized for war, “Had they stayed with us, they would not have died or gotten killed.” GOD renders this a source of grief in their hearts. GOD controls life and death. GOD is Seer of everything you do.

What can someone loan God as a loan of righteousness?
The idea of a loan is that you will be paid back in a future date. God is asking us to forsake our own interest for the interest of God in doing righteous works and forbidding evil. In return God will pay us back for our efforts. This is due to God’s mercy to allow us to be able to take such a loan from God. God doesn’t need our loan, but He thus gives the believers a chance to make a return on their investment. For instance, if God willed He could feed all the people, but He gives the believers a chance to earn credit.
[36:47] When they are told, “Give from GOD’s provisions to you,” those who disbelieve say to those who believe, “Why should we give to those whom GOD could feed, if He so willed? You are really far astray.”
[8:17] It was not you who killed them; GOD is the One who killed them. It was not you who threw when you threw; GOD is the One who threw. But He thus gives the believers a chance to earn a lot of credit. GOD is Hearer, Omniscient.
The Best Investment
[2:261] The example of those who spend their monies in the cause of GOD is that of a grain that produces seven spikes, with a hundred grains in each spike. GOD multiplies this manifold for whomever He wills. GOD is Bounteous, Knower.
[2:262] Those who spend their money in the cause of GOD, then do not follow their charity with insult or harm, will receive their recompense from their Lord; they have nothing to fear, nor will they grieve. Charity
[2:265] The example of those who give their money seeking GOD’s pleasure, out of sincere conviction, is that of a garden on high fertile soil; when heavy rain falls, it gives twice as much crop. If heavy rain is not available, a drizzle will suffice. GOD is Seer of everything you do.
[64:17] If you lend GOD a loan of righteousness, He will multiply the reward for you manifold, and forgive you. GOD is Appreciative, Clement
2:245 also reminds me of the following verses:
The Best Deal
[61:10] O you who believe, let Me inform you of a trade that will save you from painful retribution.
[61:11] Believe in GOD and His messenger and strive in the cause of GOD with your money and your lives. This is the best deal for you, if you only knew.
[61:12] In return, He forgives your sins, and admits you into gardens with flowing streams, with beautiful mansions in the gardens of Eden. This is the greatest triumph.
[61:13] Additionally, you get something you truly love: support from GOD and guaranteed victory. Give good news to the believers.
[61:14] O you who believe, be GOD’s supporters, like the disciples of Jesus, son of Mary. When he said to them, “Who are my supporters towards GOD,” they said, “We are GOD’s supporters.” Thus, a group from the Children of Israel believed, and another group disbelieved. We helped those who believed against their enemy, until they won.
