Miracles shown by Imam Ali Ridha (a.s), which prove the rightfulness of his Imamate and which are mentioned in books of Shia and which also refute the beliefs of the Waqifite sect, were the same through whose blessings some believers in Waqifite creed, like Abdur Rahman bin Hajjaj, Rifaa bin Musa, Yunus bin Yaqub, Jamil bin Darraj, Hammad bin Isa and others reverted from invalid beliefs. They were companions of the father of Imam Ali Ridha (a.s) and doubted about Imam Ali Ridha (a.s), but repented later. In the same way, those who were present during the time of the Imam, like: Ahmad bin Muhammad bin Abi Nasr, Hasan bin Ali Washa and others; they also believed in Waqf [but seeing the proofs of Imam Ridha (a.s)] they accepted his Wilayat, became bound to him and accepted the Imamate of Imam Ali Ridha (a.s) and the Imams after him from his descendants.
