Re: 10 lakh nishan?
Please read the book Haqiqatul Wahi.. A whole section of the book has been dedicated to recounting many such signs and miracles. This list is only a sample of the signs.
Please also be reminded that in order to count all these signs, you will have to read all the testimonies of the companions of Promised Messiah (as).. There are many many more which have not been recorded in written literature.. But still, start counting...
