A person approached Hazrat Imam Abu Hanifa (may Allah have mercy on him) about their plans to build a mosque and asked him to contribute. Imam Abu Hanifa excused that he cannot donate anything. In fact, he could have contributed a lot if he had wanted to.
That person insisted, ‘We do not want a lot from you; please contribute something just as a token.’
At last, Imam Abu Hanifa gave a pennyworth of a coin.
The person came back in the evening with the coin and said, ‘Sir! This coin came out to be fake.’
Imam Abu Hanifa was overjoyed and said, ‘It is fantastic. In fact, I never wanted to donate anything. There are so many mosques around, and it appears that there is an extravagance.’
