Are the supplications mentioned in the book "Kashf al-Ghummah bi Du'a al-Qur'an wa al-Sunnah wa bi al-Salah 'ala Sayyid al-Ummah" by Sayyid Hanafi Mahmoud Helwany authentic and firmly established from our Prophet Muhammad, peace be upon him, and is it permissible to recite them?

The mentioned book was authored by its writer to remind people of the virtue of supplication (du'a') and sending blessings upon the Prophet (peace and blessings be upon him), and it compiled supplications and formulas for sending blessings upon the Prophet. However, the book contained innovations (bid'ah) and Sharia-related errors, including: - Requiring the recitation of Surat Al-Fatiha and Surat Ya-Sin before supplication and sending blessings upon the Prophet. - Considering the recitation of these two surahs a reason for preservation, healing, and fulfilling needs without evidence. - Describing the Prophet's ancestors as pure and good, even though some of them died upon polytheism (shirk). - Citing a noble verse as evidence for visiting the Prophet's grave and seeking forgiveness there after his death. - Containing incomprehensible words.

Regarding the supplications mentioned in the book, some are authentically transmitted from the Messenger of Allah (peace and blessings be upon him), while others are not. It is permissible for someone who is knowledgeable and discerning regarding points of error and correctness to read the book, provided they avoid the Sharia-related violations. However, for one who does not possess this discernment, it is not permissible to read it. It is preferable to avoid reading and promoting books by people of innovation, and to restrict oneself to authentic Sunni Salafi books.
