Abbas - Tanwîr al-Miqbâs min Tafsîr Ibn ‘Abbâs
(These are they) those whom I mentioned: Abraham, Ishmael, Isaac, Jacob, Moses, Aaron, Jesus, Idris and all the prophets (unto whom Allah showed favour from among the prophets) Allah favoured them with prophethood, the message and Islam, (of the seed of Adam and of those whom We carried (in the ship) with Noah) the offspring of Noah, (and of the seed of Abraham) Ishmael and Isaac (and Israel) and of the offspring of Jacob: Joseph and his brothers, (and from among those whom We guided) those whom We favoured with faith (and chose) for Islam and the emulation of the Prophet (pbuh) i.e. 'Abdullah Ibn Salam and his followers. (When the revelations of the Beneficent) expositing the commands and prohibitions (were recited unto them, they fell down, adoring and weeping) they prostrate themselves and weep out of fear of Allah.
Those (ūlā’ika is the subject) to whom God has been gracious (alladhīna an‘ama’Llāhu ‘alayhim is an adjectival qualification of it [of the subject]) from among the prophets (mina’l-nabīyyīna, an explication of it [of the subject] functioning like an adjectival qualification in terms of import. That which follows it [mina’l-nabīyyīna, ‘from among the prophets’] up to [where] the conditional sentence begins, constitutes an adjectival qualification of al-nabīyyīna, ‘the prophets’; and so His saying … ) of the seed of Adam, namely, Idrīs, and of those whom We carried with Noah, in the Ark, namely, Abraham — [who is the] son of his [Noah’s] son Shem (Sām) — and of the seed of Abraham, namely, Ishmael, Isaac and Jacob, and, of the seed of, Israel — who is Jacob — namely, Moses, Aaron, Zachariah, John and Jesus, and from among those whom We guided and chose, that is to say, from among their number (the predicate of ūlā’ika, ‘those’, is [the following, idhā tutlā …]) when the signs of the Compassionate One were recited to them, they would fall down prostrating and weeping (these [sujjadan and bukīyyan] constitute the plural [forms] of sājid, ‘prostrate’, and bākin, ‘weeping’ [respectively]) in other words [what is meant is]: be [you] like them (bukiyyun is originally [formed from] bakūyyin, but the wāw is changed into a yā’ and the damma vowel into a kasra).
Allah, the Exalted, says that these Prophets (were favored), but this does not mean only these Prophets who were mentioned in this Surah. Rather, it is referring to all of those who were Prophets. Allah merely changes the implication of the discussion from specific individuals to the entire group of Prophets.
(they unto whom Allah bestowed His grace from among the Prophets, of the offspring of Adam.) As-Suddi and Ibn Jarir both said, "That which is meant by the offspring of Adam is Idris, and what is meant by the offspring of those `whom We carried with Nuh' is Ibrahim, and what is meant by the offspring of Ibrahim is Ishaq, Ya`qub and Isma`il, and what is meant by the offspring of Isra`il is Musa, Harun, Zakariyya, Yayha and `Isa bin Maryam.'' Ibn Jarir said, "And that is the distinction of their genealogies, even though Adam gathers all of them (as their original father). This is because among them is he who was not a descendant of those who were on the ship with Nuh, and he that is Idris. For verily, he was the grandfather of Nuh.'' I say that this is the most apparent meaning, which concludes that Idris is amongst the pillars of Nuh's ancestral lineage. The view that this Ayah refers to the ancestral lineage of the Prophets, is the fact that it is similar to Allah's statement in Surah Al-An`am,
(And that was our proof which We gave Ibrahim against his people. We raise whom We will in degrees. Certainly your Lord is All-Wise, All-Knowing. And We bestowed upon him Ishaq and Ya`qub, each of them We guided; and before him We guided Nuh, and among his progeny Dawud, Sulayman, Ayyub, Yusuf, Musa and Harun. Thus do We reward the doers of good. And Zakariyya, and Yahya, and `Isa and Ilyas, each one of them was of the righteous. And Isma`il and Al-Yasa` and Yunus and Lut and each one of them We preferred above the `Alamin. And also some of their fathers and their progeny and their brethern, We chose them, and We guided them to the straight path.)6:83-87 Until Allah's statement,
(Of some of them We have related to you their story. And of some We have not related to you their story.) 40:78 In Sahih Al-Bukhari it is reported from Mujahid that he asked Ibn `Abbas, "Is there a prostration in Surah Sad'' Ibn `Abbas replied, "Yes.'' Then he recited,
(They are those whom Allah had guided. So follow their guidance.) 6:90 Ibn `Abbas then said, "So your Prophet is one of those who have been commanded to follow them. And he is of those who should be followed.'' -- referring to Dawud. Allah, the Exalted, said in this noble Ayah,
(When the Ayah of the Most Gracious were recited unto them, they fell down prostrate and weeping.) This means that when they heard the Words of Allah, mentioning His proofs and evidences, they prostrated to their Lord in humility, humbleness, praise and thanks for the great favors they were blessed with. The word Bukiyan at the end of the Ayah means those who are crying, and it is the plural of Baki. Due to this the scholars agree that it is legislated to prostrate upon reading this Ayah, in following them and adhering to their manner of worship.
