Narated By Muawiya : Allah's Apostle said, "If Allah wants to do good for somebody, he makes him comprehend the Religion (i.e. Islam), and Allah is the Giver and I am Al-Qasim (i.e. the distributor), and this (Muslim) nation will remain victorious over their opponents, till Allah's Order comes and they will still be victorious"
Narrated Abu Huraira: Allah's Apostle said, "Neither do I give you (anything) nor withhold (anything) from you, but I am just a distributor (i.e. Qasim), and I give as I am ordered."
