Is it true that if I commit zina (hookup with some hot chick), then zina will be committed against my family? I've heard this many times. Ie. if I hookup with some girl - obviously she would be someone's daughter/sister, etc. then someone will hookup with my family member as well. Whenever I have asked for Islamic proof I failed to get any. Is there any Islamic backing to this or is it a old wives tale? Please keep it on topic. I know zina is haraam and bad so don't lecture me on it, but my question is in regards to this specific aspect. I don't think we should make stuff up just to prove something is bad (assuming there is no proof behind this). JazakAllah. Have a great day brothers and sisters.
