بِسْمِ اللهِ الرَّحْمنِ الرَّحِيمِ
Rasulullah (صلى الله عليه وسلم) once asked his Sahabah (peace be upon them)
Do you know who is poor?
Sahabah replied: The poor amongst us is he who has no money or property.
Rasulullah (صلى الله عليه وسلم) explained:
The poor amongst my Ummah is one, who will come on the Day of Resurrection with Salat, Saum and Zakat, but who had abused somebody, slandered someone, usurped the goods of another person, had shed blood or beaten another person. So this one and that one will be given a part of the aggressor's good deeds; should his good deeds fall short, before he clears what he owes then the aggrieved person's sins and faults will be transfered from them to him; and he will be thrown into Hell-Fire.
