Step-by-step explanation:
As most people know, Shah Wali Ullah was one of the most influential people in the subcontinent during the time at which Hindu-Muslim conflicts were at it’s peak. There were many more, like Sir Syed Ahmad Khan, but I had to write a report on Shah Wali Ullah and I don’t have useless time to research and write reports on Sir Syed Ahmad Khan for no reason so here you go: an article about Shah Wali Ullah and his work.
The work of Shah Wali Ullah (1703 – 1762) was very important in the revival of Islam in the subcontinent during the eighteenth century.
The most important work of Shah Wali Ullah was the teaching and preaching of the basic, pure and true meanings of Islam in ‘Madarsa’ (aka, where kids go to learn how to read the Quran) through which he trained his sons (and other kids) who continued his work through several generations. This allowed him to spread his thoughts and beliefs, even when he was dead. He sent several missionaries to different countries, and even in parts of the subcontinent since, you know, it was so freaking huge.
But he didn’t just talk into a microphone, he wrote fifty freaking one books in order to explain the proper teachings of Islam. The books presented the correct concept and beliefs of Islam in a very simple form. Besides writing books, he wrote other stuff too. Like translating the entire Holy Quran into Persian, which was the dominating language at the time. Later, his sons translated the Holy Quran into Urdu, which allowed for more people to read and understand it.
Through his teachings he corrected many un-Islamic ideas and beliefs, which had crept in the Muslim culture and society. Through his teaching he also brought different sects of Muslims, especially the Shias and Sunnis, close and emphasized the need of unity among the Muslims.
Since many Muslims at the time were separating, as a lack of knowledge and understanding of the Holy Quran, he tried to unite all of them into a single community. He did so by firstly making and finding bridges between the different beliefs of Muslims and then secondly by uniting them into a single army to defend the subcontinent, which was being attacked by the Marathas. Yeah, through his efforts he managed to persuade the Afghan ruler, Ahmad Shah Abdali to attack and defeat the Marathas in the battle of Panipat in 1761. After this defeat the Marathas could not rise again. This sign of unity inspired many future reformers to revive Islam.
His efforts made many, if not all, Muslims to unite together and made them desire a country which they could call there own. If Shah Wali Ullah hadn’t united the Muslims, Pakistan probably wouldn’t have been made, and as such Muslims would be more spread out and different from each other then ever before.
