A man from among those who were before you was called to account. Nothing in the way of good was found for him except that he used to have dealings with people and, being well-to-do, he would order his servants to let off the man in straitened circumstances [from repaying his debt]. He (the Prophet p.b.u.h) said that Allah said: We are worthier than you of that (of being so generous). Let him off.
It was related by Muslim (also by al-Bukhari and an-Nasa’i).
Allah is the most merciful, the most forgiving. He asks Muslims to be as forgiving as they expect Allah to forgive them for their sins. And whoever tries to inculcate the habit of forgiving and generosity in themselves are rewarded beyond imagination.
