ما هي أنواع الربا السبعون المذكورة في حديث النبي صلى الله عليه وسلم؟

Usury has many facets, and it has been mentioned in the noble Sunnah with different wordings. Sometimes it is "seventy doors," and at other times "seventy-three," and it has been mentioned as "seventy-two," the easiest of which is like a man marrying his mother. The gravest form of usury is dishonoring a Muslim man. These numbers are for amplification and exaggeration, not for restriction, as evidenced by the variation in narrations.
