Mufti Ebrahim Salejee saheb mentioned something thought provoking in one of his majalis this month. He was mentioning how if someone commited the unfortunate sin of zinaa and it became known, then that person will face dirty looks and comments every time he is around Muslims.
On the other hand, a person could be working in a bank which deals in interest, and yet there will be no comments on this person; in fact people may actually be envious of his wealth even though it is haraam.
And yet, Rasulullah Salla Allahu Alayhi wa Sallam has mentioned in a hadeeth something to the effect that Riba (ie interest) has seventy levels of sins, the lowest being commiting incest with ones own mother. Rather thought provoking, especially in this interest based world.
Rasulullah Salla Allahu Alayhi wa Sallam once had a long dream in which he saw a river of blood with a man wading in it. Another man was at the shore with a pile of rocks. Whenever the man in the river tried to come out, the man on the shore would throw a rock at the man in the river, causing him to go back to his prior position in the blood. Rasulullah Salla Allahu Alayhi wa Sallam was told that this was the punishment of those who dealt in interest.
May Allah Ta'aala save us all from all sins and make us into His obedient slaves. Ameen.
