The Battle of Yarmouk, fought in 636 CE, was a decisive military engagement between the Rashidun Caliphate and the Byzantine Empire. The victory of the Muslim forces under Khalid ibn al-Walid effectively ended Byzantine rule in Syria and the Levant, marking a major expansion of the Islamic state during the reign of Hazrat Umar (RA).

Hazrat Umar (R.A.) appointed Hazrat Saad bin Abi Waqqas (R.A.) as the commander-in-chief for the Battle of Qadisiyyah against the Sassanid Empire. This decisive battle was a major turning point in the Islamic conquest of Persia, leading to the eventual collapse of Sassanid power in the region.

Syed Ahmad Shaheed and Shah Ismail were martyred in 1831 during the Battle of Balakot. They were leading a movement to establish an Islamic state and resist the expansion of the Sikh Empire in the northwestern regions of the Indian subcontinent, an event that remains a significant milestone in regional history.

Haji Shariatullah was the founder of the Faraizi movement in Bengal during the 19th century. He advocated for a return to the fundamental principles of Islam and urged his followers to reject non-Islamic customs and superstitions that had integrated into local practices. His movement aimed at social and religious reform, emphasizing the strict observance of Islamic duties (faraiz) and the purification of faith among the Muslim peasantry.

The Faraizi movement, founded by Haji Shariatullah in the early 19th century, emerged in Bengal as a socio-religious reform movement. It gained significant momentum as a reaction against the oppressive economic and social policies imposed by the British colonial administration and the local zamindars. The movement sought to purify Islamic practices and mobilize the Muslim peasantry against the exploitation and marginalization they faced under British rule, becoming a significant precursor to later anti-colonial struggles.

Mohsin-ud-Din Ahmed, better known as Dudhu Mian, was a prominent leader of the Faraizi movement in Bengal. He succeeded his father, Haji Shariatullah, and played a crucial role in organizing the peasantry against the oppressive policies of British indigo planters and local landlords. His leadership significantly strengthened the movement's influence among the rural Muslim population during the 19th century.

Mohsin-ud-Din Ahmed, popularly known as Dudu Miyan, succeeded his father Haji Shariatullah. He played a pivotal role in organizing the Faraizi movement into a more structured and militant organization to protect the rights of the peasantry against oppressive landlords and colonial authorities in Bengal.

Haji Shariatullah, the founder of the Faraizi movement, declared Bengal 'Darul Harb' (land of war) under British colonial rule. He argued that because the region was no longer under Muslim governance, the conditions required for the performance of congregational Friday (Jumu'ah) and Eid prayers were not met. This was a significant socio-religious stance aimed at mobilizing the Muslim peasantry against colonial influence and religious innovation.

After the death of Haji Shariatullah, his son, Muhammad Muhsin, popularly known as Dadhu Mian, took over the leadership of the Faraizi movement. He transformed it into a more organized and militant socio-religious movement, focusing on the rights of the peasantry against oppressive landlords in Bengal.

Shah Waliullah of Delhi was a preeminent Islamic scholar and reformer. He dedicated his life to the revival of Islamic thought and the purification of the faith from un-Islamic customs and innovations that had crept into the society of his time. His work laid the foundation for subsequent reformist movements in the Indian subcontinent.
