Al-kakazai, I've came across lies that you have mentioned on your blog regarding Mawlana Shah Ismail Shahid (may Allah have mercy on him) and Taqwiat al-Iman. You have quoted a [fabricated] letter that was written to Fazl Rasul Bayaduni. It should be kept in mind that Fazl Rasul Bayaduni was a British agent whose task was to link the movement of Imam Syed Ahmed shaheed (may Allah have mercy on him), and the Muhadditheen of Dehli to Najd. Ahle biddah should not forget that Imam Shah Abdul Aziz Dehlwi (may Allah have mercy on him) held same beliefs as that of Shah Ismail shaheed and after Imam Shah Abdul Aziz gave fatwa that India is Dar al-Harb, it was Syed Ahmed shaheed and Shah Ismail shaheed who waged Jihad against the British.
A murid of Fazl Rasul Bayduni writes in his biography, Akmal al-Tarikh that he would get paid 260 monthly for his services to the government. Fazl Rasul Bayaduni was also the head of department of Ifta for some period of time, which was run under the supervision of the British government.
Dr. Allamah Khalid Mahmud writes:
"Fazl-e-Rasūl Badāyūnī worked for the British and his plan against the Hadīth scholars of Delhi remained unsuccessful. Hadhrat Shāh Walī Allāh was not alone in propagating tawhīd (monotheism) and the sunnat, and opposing shirk and bidat. Among his students were famous pious people such as..."
Fazl Rasul Badayuni also spread his venom against Imam Shah Waliullah Delhwi (may Allah have mercy on him) as he says:
"The conclusion of everything that Shāh Walī Allāh has written shows that he is against the Ahl al-Sunnat wa al-Jamāat. Shāh Walī Allāh’s pious children [he is being sarcastic here] have not published and distributed these types of books (by Shāh Walī Allāh), and have kept (these books) hidden. It is as if they have veiled those words of their father that were unveiled."
Fazl Rasool Bayaduni didn't even spare Imam Rabbani Mujaddid Alf-e-Sani (may Allah have mercy on him) and wrote alot of filth against the great Imam.
Not just Fazl Rasul Badayuni, but most of the scholars of Badayun were working for the British. Famous British historian Peter Hardi in his book The Muslims of the British India writes about Abdul Hamid Badayuni and Abdul Majid Badayuni:
“For their activates the brothers Abdul Hamid and Abdul Majid were well rewarded by the government. Medals denotation the title of Shams-ul-Ulama dangled from their turbans, while for his anti-Khilafat work Abdul Majid was one of the most rewarded men in the province. At a provisional durbar in 1922, he received from the Harcourt Butler both a robe and a sword of honor.”
Ofcourse, Ahmed Raza Khan could not be invited since he had already passed away in 1921. It wouldn't be wrong to say that Ahmed Raza Khan was a true successor of Fazl Rasul Badayuni.
