Wakf Board Land Issue.

Wakf Board sold his land to person 'A' in seventies, mentioning that they have money requirement. It is also stated that the land can be used by buyer (person A) on his will. Person A sold the land to 'B' in eighties with proper registration. B sold the same land to one of my relatives (person C) in 1992. Since then, no construction /nothing has been done to this land. Now they wanted to sell this land again to someone. But no one is ready to buy this land because of this land/property has no mutation. They try their best to get mutation from the concerned Block but the Patwari/Halka Karamchari is not ready to change the record in KHATIAN. Many persons came and go when they found that this land has no mutation. In concerned Block it shows (in records) it is Wakf Board land. Ward Counsellor also intimidate/terrify the people who want to buy the land saying that he will inform it Wakf Board and Circle Officer in this regard. In fact, this land is just close to (my) home and I want to buy this land. They too want to sell to me because no one is ready to buy this land because of NO MUTATION. Please suggest me that should i buy this land or not and what can be the repercussions. It does not seem that mutation is possible in near future. If it does not happen and I buy it without mutation , can it create a problem in future. What is the procedure to get the Mutation of land like this? Please suggest me with full details. Thanks a lot.....
