i know someone who did it in her right mind and both of them are very very content mashallah … and no there wasnt any holly/bollywood love shove kinda thing involved…i know it is hard thing to do but if you two are starting fresh and bringing lets say only even 2k each per month then i dont see why cant just you two have very comfortable life to begin with …
and obviously i didnt have any runaway kinda students in my mind when i typed my above response…finish studies first, work for a while and save as much as you can and put it towards the down payment for your house/appt once u get married … i see many are doing it these days
and ON the Topic .. i m in favor or rukhsati right after the nikkah… a gap of a day or two is fine… thats it.
