The Family Of Imran - 3:181
"Allah hears the words of those who say: "Allah is poor and we are rich". We will record what they say and their unjust killing of the prophets and We will say: "Taste the torment"."
It is understood that the Children of Israel mocked the expression "lend to Allah" and ridiculed Allah by characterizing Him as a pauper who asks for a loan:
The Table Spread/5:12
"Allah had taken a promise from the Children of Israel and We sent twelve leaders from among them. Allah said: "I am with you if you observe the prayer, pay the zakat, believe in My messengers and respect them, and lend to Allah a good debt. I will cover your sins and give you gardens in which rivers flow. So whoever of you disbelieves after that has gone astray from the right path."
