http://bayyinah.tv - For more videos by Ust. Nouman Ali Khan The definition of ungratefulness is never being appreciative of all the gifts Allah gave us and taking them for granted. In Surat Ar-Rahman, explains Nouman Ali Khan, Allah tells us to be grateful or else you would be defying Him, and the punishment for that may not be in this world. You will not get away with such transgressions and if you think you can escape on judgment day, you are mistaken. The more grateful you are to Allah’s many blessings, the more doors he will open for you.
