The Messenger of Allah said:

“One Dirham surpassed one hundred thousand Dirhams.” They said: “How?” He said: “A man had two Dirhams; he gave one of them in charity; and another man went to part of his money and took out of it one hundred thousand Dirhams and gave them in charity.”

The man who does not have but two Dirhams and gave one of them for the sake of Allah, favoring the reward of Allah has more reward than the wealthy who gave in charity one hundred thousand, which is little compared to the plenty of money he had.

If it were not for the strong certitude of the first, he would not give half of his money. Had it not been for his strong trust in Allah, his belief in the Hereafter and the reward from Allah, and the occupation of his heart with the Hereafter, the reward of this single Dirham would have not surpassed the reward of one hundred thousand Dirhams, which the wealthy paid in charity out of his own (abundant) money.
