The Heights - 7:58
The good land produces crops by the permission of your Lord. But the bad land does not yield anything useful. Thus do We make clear the verses for a grateful people.
What is the intention?
The Cow/2:261
The example of those who spend their money in the Way of Allah is like that of a grain which yields seven ears of grain, one hundred in each. Allah gives in multiples to whomever He wills. Allah is Generous, Knowing.
The Cow/2:265
The example of those who spend their money because they want to earn Allah´s pleasure and they are convinced of it is like the example of a high-yielding garden which yields double its produce when it receives abundant rain, and is content with the dew even if it does not receive abundant rain. Allah sees what you do.
The Cow/2:264
Believers! Do not waste your charity by insulting and persecuting, like the one who does not believe in Allah and the Last Day but gives charity to show off to the people. The example of such behavior is like a rock on which dust has accumulated so that a heavy downpour leaves it bare. They will gain nothing from what they have done. Allah does not guide the disbelieving people.
