Mina

Q: I have read a fatwa of Darul Uloom Deoband that Makkah and Mina are separate places till the day of judgement and also opinion of yours is same. So as there is another opinion which states now Mina is part of Makkah (only for prayer to be full or Qasar).

1. Does that mean that the fatwa which says stay in Makkah before Haj is calculated is intact and will not change?

2. I also came to know that these are differences in fiqhi masaail and it has been there since the Sahaaba, so one should follow anyone and shouldn't object to others.

3. Will a person be sinful if he follows anyone?

Q: In the recent past the Saudi authorities have started keeping haajis in tents put up at Muzdalifah before they proceed to Arafat because of lack of space at Mina. Will the stay of these hajjis be considered as having been spent at Mina like those who actually stay at Mina proper. Secondly hajis returning from Arafat also spend the night in the same area where the tents have been erected at Muzdalifah. Will these hajis be considered as having fulfilled their wuquuf of Muzdalifah (as in reality it is actually proper Muzdalifah).
