Translation of the verse 37 from Surah An-Najm : Number of verses 62 - - page 527 - Part 27.
And of Ibrahim (Abraham) who fulfilled (or conveyed) all that (what Allah ordered him to do or convey),
And [of] Abraham, who fulfilled [his obligations] -
(53:37) and of Abraham, who lived up to the trust? *36
*36) In the following verses a resume is being given of the teachings sent down in the Books of the Prophets Abraham and Moses. The Books of Moses signify the Torah. As for the Books of the Prophet Abraham they have become extinct and no mention of them is found even in the holy scriptures of the Jews and Christians. Only in the Qur'an at two places have some parts of the teachings contained in the Books of the Prophet Abraham been cited, here and in the concluding verses of Surah AI-A`la.
