What is the ruling on reading the book "Dala'il al-Khayrat," and is the prayer mentioned in it for Friday, whose reward is an accepted Hajj and the freeing of a slave from the progeny of Ismail, authentic?

We have previously expressed our opinion regarding the aforementioned book. This also includes what Abu Dawud and others narrated from Aws ibn Aws, who said: The Prophet, peace and blessings be upon him, said: "Indeed, among the best of your days is Friday, so send abundant blessings upon me on it, for your blessings are presented to me." They said: "O Messenger of Allah, how can our blessings be presented to you when you have decayed?" — they said, meaning "become old and worn out" — He said: "Indeed, Allah, the Blessed and Exalted, has forbidden the earth from consuming the bodies of the prophets."
