Shah Waliullah Muhaddith Dehlavi is a well-known scholarly personality of the subcontinent. He was primarily a Hanafi Muslim. The era in which he was born was a period of taqlidism and Hanafi jurisprudence was patronized by the government. Jurisprudents like Shah Waliullah were brought up in this school of thought. But when he went to Makkah for Hajj, he learned Hadith from the Arab sheikhs, from which a movement arose in his nature against the status quo of imitation. So, on his return from there, he first explained this to the people of the subcontinent through his writings. That religion cannot be confined to any one jurisprudence, rather it is with the four Imams. This was the first formal attempt against static imitation in the subcontinent. After that, Shah Sahib devoted his entire life to popularizing the Qur'an and Sunnah. And the expediency has been highlighted. This book is a summary of the great document of human welfare in the light of personal and collective problems, ethics, sociology and economics. The original book is in Arabic, which has been translated by many scholars into Urdu. And at that time there was a need to have a rate, so the author has fulfilled this deficiency. The book under comment "Rahmatullah Al-Wasaa Sharh Hajjatullah Al-Balaga" is the authorship of Maulana Saeed Ahmad Palanpuri, the teacher of Dar Uloom Deoband, in which he has described this great work of Shah Sahib. This book consists of five thick volumes. And in view of its usefulness, it is being offered to the readers. We pray to Allah Almighty to accept this great service of the author, translator and commentator in His presence and to increase their good deeds. Ameen (Rasakh).
