Ghazwa-e-Hind

Ghazwa-e-Hind is a notorious prophecy (and sometimes conspiracy theory among Hindu nationalists) that is mentioned in some "good" hadiths predicting a great battle in India between Muslims and Hindus, resulting in a conquest of the whole Indian sub-continent by Muslim warriors. The conquest is supposed to occur before the end-times and create an Islamic caliphate resembling the social order that existed at the time of Muhammad by imposing sharia, although many scholars consider these predictions to have already occurred during sultanate and Mughal times. One of the narrators Kab Ahbar is a Jewish convert to Islam who is concerned with Messianism without rejecting Jesus and victory of monotheism over polytheism.

According to the prophecy
According to many historians and scholars, this mostly refer to rule of the Delhi Sultanate, Bengal Sultanate and the Mughal Empire, most notably emperor Aurangzeb's reign.

The final battle starts in Syria and the troops march forward from Jerusalem to Hindustan (India). The warriors destroy the land of Hind; possess its treasures, then the King of Jerusalem uses those treasures for the décor of Jerusalem. The troops bring the Indian kings in front of the King of Jerusalem. His warriors, by King's order, would conquer all the area between East & West.

Later, the Antichrist will appear in India and try to rule the world. Isa ibn Maryam, i.e Jesus Christ, will kill him and save the world.

According to scholars
Many Muslim scholars believe that if indeed it is a hadith, then that also has happened long ago in 600-700 CE when Mohammad bin Qasim attacked India. After that there have been a number of attacks on India from Central Asia by Muslim rulers, and India was under Muslim rule for a long time. Khurasan Hadith had been cited to mobilize Muslim soldiers. Sayings attributed to the Prophet Muhammad were often transmitted orally; formal, written compilations did not emerge until more than a century after his death.

Other Indian Muslim clerics have offered alternative explanations of the Hadith. Maulana Abdul Hamid Numani of the Jamiat ul-Ulema-i Hind (Society of Indian Islamic Scholars) says that this Hadith was fulfilled at the time of the Four Righteous Caliphs, when several companions of the Prophet came to India in order to spread Islam. Mufti Sajid Qasmi, professor at Dar ul-Uloom Deoband, believes that the Hadith might also refer to the invasion of Sindh by Arabs under Muhammad bin Qasim in the eighth century. In the expedition of Ibn Qasim there is a pious general Attiya Awfi who was involved in a relationship like that between Plato and Alexander.

On the other hand, Maulana Mufti Mushtaq Tijarvi of Jamaat-i Islami India has suggested that the hadith is not genuine at all and it is just a fabrication intended to justify Qasim's invasion of the Indian subcontinent.

Usage by terrorists and Islamic extremists
The term Ghazwa-e-Hind is frequently used by militant groups in Pakistan and Kashmir to justify attacks and terrorism in India in the name of the "prophecy".
