Al-Matalib al-'Aliyah 678 — The virtue of Friday and the hour

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that he was asked about the blessed hour that occurs on Friday (for acceptance), and he replied: "Allah knows best. Indeed, Allah Almighty created Sayyiduna Adam (peace be upon him) on Friday after Asr, and He created him from a handful of soil which He took from the surface of the whole earth. Do you not observe that among his descendants some are of red complexion, some black, some wicked and impure, and some good and pure? Then Allah, Lord of Might, took a covenant from him, but he forgot it, and because of this forgetfulness he was named insan (human). By Allah, the sun had not yet set on that day before he was sent down to the world."
Imam Musaddad narrated it; all the narrators of its chain are thiqat (trustworthy), and it is a sahih mawquf narration.
