.Shahwaliullah worked to revive Islam with both knowledge and force.
.Syed Ahmad Barelvi chose to use force and weapons in order to revive Islam in the sub-continent.
.Haji Shariatullah chose to use peaceful means to revive Islam by using his own knowledge and Tableegh.
> Overall, in my judgement, Shahwaliullah was most successful among them as he was able to teach Islam in his father's institute, was able to encourage others to do same as Syed Ahmed studied under his sons, was successful in making Holy Quran accessible by translating it in Persian and finally was successful in defeating Maratha forces in 1761.
