Famous Deobandi Sufi shaykh and scholar, Mawlana Hussain Ahmad Madani (RAH) , mentioned the danger of paper based money in the book " prisoners of Malta ". He gave this warning during the second world war when the Murabitun was not even bron !!! So, I think , the hoax of paper money is already well-known to some Deobandi scholars . A question may arise that why Deobandi Movement could not initiate something like Murabitun has done. This , I think , depends on the tawfiq granted by Allah. It is sign of Allah's great wisdom that He does not put all eggs in the same basket. So you find a good number of Islamic groups each of which giving service to the establishment of Islam in various ways. As long as each of these groups respect each other and does not make mistake of " seeing the trees , not the forest ", then there will no bad feeling .
