TUHFATUL HIND AND TAQWATUL IMAN....
Hazrat Maulana Ubaidullah Sindhi writes:
The first book that gave me a correct understanding of Islam and I became a Muslim before the age of sixteen, living in a Hindu society, is “Tuhfatul Hind”.

My namesake author of Tuhfatul Hind, after quoting the polytheistic beliefs and customs of Hinduism, has quoted an objection from Hindus that there are polytheistic practices and customs among Muslims as well? The author has answered this briefly by saying that whatever we have said about Hinduism is taken from their authentic books, but what is presented in response to it is not taken from the authentic books of Islam, but rather the practices and customs of Muslims, for which Islam is not responsible and no evidence can be presented for them from the Quran and Hadith.

At this point, my companion (who was a new Muslim like me) felt the need to investigate whether the authentic books of Islam were really completely free from this issue and there was no evidence of these practices and customs in them. At this point, there was a need for a book that presented the monotheism of Islam only with reference to the Quran and Hadith. Fortunately, after Tuhfatul Hind, the second book that came to our hands was Maulana Ismail Shaheed's "Taqwatul Iman", which was the definitive answer to this question and from which we came to know that the monotheism of Islam is completely pure and the Quran and Hadith are completely free from these practices and customs of Muslims.
