Assalamu 'alaykum. I hope i can get Shaykh Abu Hasan view and opinion. I just want to know, why is there a difference in the scholars of Deoband and most sunni scholars about buying mortgage house in UK/Western countries. Many sunni scholars deem it permissble today, and many hanafi scholars of deoband deem it haram, why this difference when they both follow hanafi madhab. Secondly, how many sunni scholars still deem it impermissble today. Thirdly, is the ruling same for a normal muslim and scholar/muslim who is working for din in dar al-harb to make hijrah if its becoming difficult to act on sharia, meaning faraidh/wajib.
