Life and Times of Imam Abu Hanifa
One day a man came to the Imam and said: “I kept some money somewhere in my house, but do not remember exactly here. I now need the money badly. Please tell me how I can find it.” Brother,” protested the Imam, “do not find this kind of problem mentioned in fiqh. Why have you come to me for advice?” but on further entreaty by the man he advised him to pray throughout the night. The man, accordingly, went home and started praying, he had prayed for a little while when he suddenly remembered where he had put the money. So he ran to the Imam and told him of the efficacy of his advice.
