[Pooya/Ali Commentary 9:32] False teachers and preachers try to distort the message of Allah by the false words (conjectures) of their mouths, so that they may put out the "light", for they are people of darkness and ignorance, but Allah has perfected His light- light implies the light of guidance completed and perfected at Ghadir Khum by declaring the wilayah of Imam Ali (see commentary of Ma-idah: 67). Through the Holy Prophet and his Ahl ul Bayt, Allah made His (true) religion a signal success. For the men of understanding the true teaching of Islam is the best code of law for human society. The ultimate triumph of Islam will be witnessed when Imam Muhammad bin Hasan al Mahdi al Qa-im, the last true successor of the Holy Prophet, will come in this world, with the permission of Allah, to unite the whole mankind as a single community, to live in peace and harmony, doing away with injustice, exploitation and polytheism, guided by the divine laws made by Allah. The divine laws have been perfected and completed and named Islam, after which the laws given to other people in the days of earlier prophets, preceding the Holy Prophet, became inoperative and subservient to Islamic laws. In theory and practice Islamic laws and teachings surpass all creeds. However much the polytheists and the hypocrites may try to stop the ultimate victory of Islam under the guidance of the living Imam, the al Qa-im, it is certain to take place. Verse 28 of Fat-h and verse 9 of Saff also give the glad tidings of the ultimate victory of Islam when al Qa-im comes in this world. Abu Dawud, Tirmidhi, Ahmad ibn Hanbal, Abu Yula, Hakim, Suyuti, Tabarani, Darqatni, Abu Nu-aym, Khatib and Ibn Asakir and many others have accepted the fact of the ultimate rule of Imam Mahdi, who is the last of the twelve successors of the Holy Prophet from among his Ahl ul Bayt. Even the precursor of Wahabi sect, Ibn Taymiyah, has accepted as true all the traditions pertaining to the "reign of Imam Muhammad bin Hasan al Mahdi" (refer to his book "Majmu-atul Fatawa".) Also refer to the commentary of al Baqarah: 124.
