Aḥmad Riḍā Khān states in his treatise al-Kawkabat al-Shihābiyyah:
“Wahhābīs are attributed to ‘Abd al-Wahhāb Najdī. Ibn ‘Abd al-Wahhāb was their first teacher. He wrote Kitāb al-Tawḥīd, in which he treated all Muslims apart from his vile group as open Mushriks…Taqwiyat al-Īmān is a translation of this very Kitāb al-Tawḥīd.” (Fatāwā Riḍawiyyāh, Riḍā Foundation, 15:235)
In Sayf al-Jabbār, Aḥmad Riḍā Khān’s predecessor, Fāḍl al-Rasūl Badāyūnī, claimed Taqwiyat al-Īman was akin to a commentary of Kitāb al-Tawḥīd.
The reality is Taqwiyat al-Īman and Kitāb al-Tawḥīd are two very different books. Refuting these preposterous claims of Badāyūnī and Barelwī, Mawlānā Manẓūr Nu‘mānī highlights and explains the “massive difference in the nature” (naw‘iyyat mein boht barā farq) of the two works. (For more detail, see: Shaykh Muḥammad ibn ‘Abd al-Wahhāb aur Hindūstān Ke ‘Ulamā’ e Ḥaqq, p. 66-8)
This is thus either an example of Aḥmad Riḍā Khān’s sloppy research or a further example of his deception and lies.
