Wo actually khud taqleed nai krna chah rhe. Unka kehna he ke jab hmare akhri imam zamana (as) he to hum q kisi ko follow kre. Baqi bat rhi shia hone ki, Alhamdulillah wo proper azadar he baqi sb jo imam farmate he unpe amal krte he lekin sirf taqleed isi waja se nai krte k Imam (as) ko sirf follow kre. Yha pr ek yhi masla he

This is really a matter of concern because Ayatullah Sistani’s Fatwa is as follows that, “ If a person performs his acts for some time without taqlid of a Mujtahid, and later follows a Mujtahid, his former action will be valid if that Mujtahid declares them to be valid, otherwise they will be treated as void.”
I’ve a question; as we know that the life and system today’s we follows is same as at the time of Imam a Masoom (a.s). If anyone says it’s same then let me ask three issue with is very common now a days:
What should we do being a true Muslim.
1- At the time of Imam e Masoom medical science had not discovered the issue of artificial insemination or IVF or IUI not today if any couple do not have child and their life is fading lots of problem due to not having child in such situations what they have to do? Do they do IVF or not ? If not then why ? If yes then on what ground if Islamic shariaya? Because niether we have any verse in the holy Quran regarding this issue nor we have any direct Hadith from a Imam e Masoom.(a.s).
2- A person is a chain smoker and shariat says inhaling any dust or smoke which passes through our throat can invalidate our fast but same time there is a electronic cigarette which has neither smoke nor dust particle so does a person allowed to smoke electronic cigarettes while fasting?
3- Gelatin commonly used substance in hundreds of our daily food products also we know gelatin is abstracted from either halal animal or Haram. In this case what should we do? Who can tell gelatins is allowed or not ? Who can tell there is transformation taken place or not?
All these issue they can find in any Hadith directly if anyone can capable to show them in any Hadith then there are still many issue that really this Hadith is correct or not. Source of Hadith is true or not , Hadith has been said while Imam E Masoom was in Taqqaiya or normally he said.
Religion is not a play or sport that anyone can deal with it.

Again I’m saying as long as shariat concern you can do Nikah but you are gonna live with a person who’s faith and idea and views in Religion is 180 degree different from you.
