Sahl Ibne Adbullah Tusturi Rahmatullah alaihe used to spend liberally in the path of Allah Ta'ala. His mother and brothers complained to Abdullah Ibne Mubarak Rahmatullah alihe that Sahl wanted to spend everything and they feared he would become a pauper. Abdullah Ibne Mubarak Rahmatullah alihe enquired from Sahl Rahmatullah alihe about the matter. The lattar asked Abdullah Ibne Mubarak, "If a person wanted to migrate from Madinah to the city of Rustaqq in Persia, where he had already purchased land, would he leave anything behind in Madinah?" The reply was that nothing would be left behind. Sahl Rahmatullah alaihe then said that was his real purpose. While the people thought he was going to migrate to another place, he had actually meant transfer to the next world. In these days, people have personal experience of it that when people who wish to move permanently from one country to another (eg. England to Canada) by their own choice, they try to transfer all their belongings and property, buildings, etc, by exchanging with those at the new locations, before actual migration. This is exactly the state of affairs of every single person leaving this world. As long as he is living, he has the power to transfer his property and belongings, etc., to the next world (Akhira).

Such was also the case of Abu Bakr (RA) who gave away everything in the path of Allah. We can't immitate these individuals to the full extent, however we can always try. May Allah give us the ability to be generous in giving charity.
