What is the ruling on guaranteeing a loan that is riba (usury or interest) when the guarantor did not know it was forbidden?
Machine translationRead the Arabic original
The questioner:
A relative of mine took a loan from the bank with interest, and I guaranteed it with my signature.
The Shaykh:
You guaranteed it.
The questioner:
I guaranteed it with my signature, and then I learned that it is forbidden. Is there a sin on me?
The Shaykh:
Yes, you cooperated with him in riba. If he took a loan with riba and you guaranteed it, you have cooperated with him in sin and aggression. The Prophet (peace and blessings be upon him) cursed the one who eats riba, the one who gives it, the scribe, and the two witnesses, because they cooperated with him. So you must cancel your guarantee. Cancel your guarantee and say, "I am retracting my guarantee because I learned that it is forbidden, and I do not cooperate in what is forbidden."
