The Scriptures of Ibrahim (Peace be Upon Him)
Question

                What are the Scriptures of Ibrahim (peace be upon him)?
Praise be to Allah.
    The Scriptures of Ibrahim (peace be upon him) are the 
    Scriptures that Allah revealed to His Prophet Ibrahim (peace be upon him); 
    according to the scholars, most of what they contain were exhortations, 
    wisdom and lessons. 

    Our Lord, may He be glorified and exalted, has mentioned them 
    in the Quran in a number of places, some of which refer to them in general 
    terms and some in more specific terms. 

    As for the general terms, it is where Allah says 
    (interpretation of the meaning): 

    “Say (O Muslims): We believe in Allah and that which has been 
    sent down to us and that which has been sent down to Ibrahim, Isma’il, 
    Ishaq, Y’aqub, and to Al-Asbat [the offspring of the twelve sons of Y’aqub], 
    and that which has been given to Musa and ‘Isa, and that which has been 
    given to the prophets from their Lord. We make no distinction between any of 
    them, and to Him we have submitted (in Islam).” [2:136] 

    And He says (interpretation of the meaning): 

    “Say (O Muhammad (peace and blessings of Allah be upon him)): 
    We believe in Allah and in what has been sent down to us, and what was sent 
    down to Ibrahim, Isma’il, Ishaq, Y’aqub  and Al-Asbat [the offspring of the 
    twelve sons of Y’aqub] and what was given to Musa, ‘Isa  and the prophets 
    from their Lord. We make no distinction between one another among them and 
    to Him (Allah) we have submitted (in Islam).” [3:84]. 

    As for the place where they are mentioned clearly and 
    specifically, it is in Surat al-Najm, where Allah says (interpretation of 
    the meaning):

    “Did you (O Muhammad (peace and blessings of Allah be upon 
    him)) observe him who turned away (from Islam)?

    And gave a little, then stopped (giving)?

    Is with him the knowledge of the unseen so that he sees?

    Or is he not informed with what is in the Pages (Scripture) 
    of Musa,

    And of Ibrahim who fulfilled (or conveyed) all that (Allah 
    ordered him to do or convey):

    That no burdened person (with sins) shall bear the burden 
    (sins) of another.

    And that man can have nothing but what he does (good or bad).
    

    And that his deeds will be seen.

    Then he will be recompensed with a full and the best 
    recompense.” [53: 33 – 41] 

    And in Surat al-A’ala, where Allah says (interpretation of 
    the meaning): 

    “Indeed whosoever purifies himself (by avoiding polytheism 
    and accepting Islamic Monotheism) shall achieve success,

    And remembers (glorifies) the Name of his Lord (worships none 
    but Allah), and prays (five compulsory prayers and nawafil(voluntary 
    prayers)).

    Nay, you prefer the life of this world,

    Although the Hereafter is better and more lasting.

    Verily, this is in the former Scriptures —

    The Scriptures of Ibrahim  and Musa  (peace be upon them).” 
    [87:14-19]. 

    Ibn Jarir al-Tabari (may Allah have mercy on him) said:

    What is meant by Scriptures here are the books of Ibrahim and 
    Musa. End quote. Jam’i al-Bayan. 

    Al-‘Allamah al-Ameen al-Shanqeeti (may Allah have mercy on 
    him) said:

    “… and what was sent down to Ibrahim”: it is not explained 
    here what this was that was sent down to Ibrahim, but it is explained in 
    Surat al-A’ala that it was Scriptures, and that among what it said in those 
    Scriptures was: “Nay, you prefer the life of this world, although the 
    Hereafter is better and more lasting” and that is in the verse where Allah 
    says (interpretation of the meaning):

    “Verily, this is in the former Scriptures —

    The Scriptures of Ibrahim  and Musa  (peace be upon them).” 
    [87:14-19]. Adwa al-Bayaan. 

    The Prophet (peace and blessings of Allah be upon him) has 
    told us about the history of its revelation, as it was narrated from 
    Wathilah ibn al-Asq’a that the Messenger of Allah (peace and blessings of 
    Allaah be upon him) said: The Scriptures of Ibrahim (peace be upon him) were 
    revealed on the first night of Ramadan, the Torah was revealed on the sixth 
    of Ramadan, the Gospel was revealed on the 13th of Ramadan, and the Quran 
    was revealed on the 24th of Ramadan[Ahmad]. 

    In some weak hadeeths (narrations) and in some reports from 
    the Tabi’in (successors) there are quotations from the Scriptures of 
    Ibrahim, and it is most likely that they were narrated from the books of the 
    children of Israel which, even if they are sound, indicates that the main 
    subject matter of the Scriptures of Ibrahim is wisdom and exhortation. 

    Dawud ibn Hilal al-Nusaybi says: 

    It is written in the Scriptures of Ibrahim (peace be upon 
    him):

    “O world (dunya), how insignificant you are to the righteous 
    to whom you adorn yourself. I created in their hearts hatred towards you and 
    dislike for you. There is nothing in creation that is more insignificant to 
    Me than you. Everything about you is insignificant; you are bound to perish; 
    I decreed the day I created creation that you would not last for anyone, and 
    no one would last for you, and even if the one who loves you tried to hold 
    on to you, glad tidings to the righteous who showed Me what they have of 
    contentment in their hearts and they showed Me what they have of sincerity 
    and righteousness. Glad tidings to them: I have no reward for them when they 
    come to me out of their graves except light running ahead of them, and the 
    angels surrounding them, until I grant them what they hope for of My mercy. 
    Al-Zuhd, by Ibn Abi’l-Dunya. 

    It says in al-Mawsoo’ah al-Fiqhiyyah: with regard to the 
    Scriptures of Ibrahim and Dawud, they were exhortations and proverbs, with 
    no rulings in them, so they are not included among the books which contain 
    rulings. End quote. 

    Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said:

    The Scriptures of Ibrahim are Scriptures which Allah revealed 
    to Ibrahim, in which there are exhortations and rulings. End quote. Liqa’at 
    al-Bab il-Maftuhah. 

    And Allah knows best.
