What is the ruling on one who calls riba (usury or interest) by a name other than its own, and is it permissible to pray behind him if he is an imam?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: What is the ruling on one who calls riba (usury or interest) by a name other than its own? And is it permissible to pray behind him if he is a regular imam?

Answer:
No, if he calls riba (usury or interest) by a name other than its own, there is a great danger for him; he may become an apostate because he has made riba (usury or interest) permissible by calling it by another name in order to make it permissible. Making riba (usury or interest) permissible is disbelief, may Allah protect us from it. It is not permissible to resort to subterfuge regarding what Allah has forbidden; changing names is a form of forbidden subterfuge. Therefore, one does not pray behind him, and he does not serve as an imam. Yes.
