Abdurrahman if you uphold an obvious forgery as truth,
then you have no value for history or truth.
It will not convince any reasonably man, as it is pathetic and diminishing to your own faith. something is called a fogery or a real document based on your opinion and not on research. If your willing to uphold lies as truth, who says that you won't do it with other material?
How can you trust someone's sincerity of devotion when he builds them on lies?
