Arrival of Islam in the Indian Subcontinent
During the era of Hazrat Uthman (ra), Islam reached the Indian subcontinent. Imam Yusuf writes in his book, Al-Kharaj, with reference to Imam Zuhri that Egypt and Syria were conquered during the era of Hazrat Umar (ra) and Ifriqiya, Khorasan and Sindh were conquered during the era of Hazrat Uthman (ra).
(Imam Abu Yusuf, Kitab al-Ikhraj, Fasl fi Qital Ahl al-Shirk… [Al-Maktabah al-Taufiqiyyah, 2013], p. 218)
There is a narration in regard to the arrival of Islam in the Indian subcontinent as follows:
During the era of Hazrat Uthman (ra), Hazrat Abdullah bin Muamir was given an army under his command and sent to Mukran and Sindh, where he demonstrated great valour and bravery in the conquest of Mukran. Later, he was appointed as the governor of these newly conquered lands.
(Muhammad Ishaq Bhatti, Barr-e-Saghir mein Islam ke Awwalin Nuqush, 2009, p. 63)
In regard to Hazrat Mujashi bin Mas‘ud Sulammi it is written that whilst leading a Muslim army, he fought a Jihad against the opponents of Islam in Kabul, the capital of modern-day Afghanistan. According to historians, Kabul was considered a part of India in those days. During the era of Hazrat Uthman (ra), Hazrat Mujashi fought against the opponents of Islam in Balochistan, a province of Pakistan and also conquered the neighbouring area of Sistan. Thereafter, the Muslims began to live in these areas of the Indian subcontinent and considered it as their homeland.
