and have you thought of what will happen to muslims living in india in return?
for all practical intents and purposes, it's just wishful thinking. we are in this situation due to our own deeds and buying into the aasteen ke saanp congress's post independence hindu Muslim bhai bhai model; and our brethren from the Arab world competing with us in lacking in shame and gheirah; now, with valentine's day and halloween being actively promoted by Arab nations, they'd probably burn down an effigy of ravana in 2023 dussehra. it would work wonders if they merely banned and blocked all indian entertainment and bollywood, let alone place sanctions!
(Huzoor Mufti Azam Hind might not have been vocal in the sense of doing political commentary, but masha Allah as a scholar and guide, even then he instilled gheirah and shame in Muslims against hindus as best as he could with anyone who bothered to listen, imho he was the proverbial last of the mohicans who taught Muslims shame and gheirah and warned against hindus in an age when people were drunk on indian nationalism)
as for the actual what-if question,
1. it's not rainbows and unicorns for indian Muslims right now in any case,
2. the only OIC countries whose sanctions will have any meaningful impact on ground are the khaleej nations and iran, followed by turkiye, egypt and malaysia. nothing more can be realistically expected other than some elementary lip service from turkiye or malaysia - best case scenario,
3. i feel regardless if such a thing happens or not, unless the rashtra crashes and dismantles under its own gobar, we are heading down the path of the rohingya, bosnians etc. i think we will see one of the two in our lifetimes - either the dismantling of the rashtra or a seriously pitiful plight of the indian Muslim wal 3eyadhu billah. it's not about if it will happen, but when! Muslims nationwide are today in more or less the same situation as kashmir used to be in the 80's and 90's, and it's heading further downhill.
4. there's no such thing as staying 100% safe (either life or property) and trying to win a political conflict.
what's the conflict btw? defense against totally uncalled for and unprovoked acts of extreme aggression, steadily and exponentially increasing over the last 30 years.
from the gobar guy's perspective - he always had it his way post 1947 - the Muslim (speaking abstractly) was utterly powerless and sidelined, and to make it easy for them, bought into the bhai-bhai model too, there really was no practical need of the BJP or the RSS from their perspective, to maintain any sort of power or supremacy! so what exactly did the indian Muslim do to deserve this?
5. the average hindu businessman and the millionaire in the khaleej is going to be more shattered by a freezing of his bank accounts and his property confiscated than a poor Muslim rickshaw wala having his rickshaw torn apart. they are lowly cowards and don't have the heart of the Muslim
