"When the "Surat-An-Nasr", 'When comes the Help of Allah and the conquest,' had been revealed to the Prophet (ﷺ) he did not offer any prayer except that he said therein, "Subhanka Rabbana wa bihamdika; Allahumma ighfirli (I testify the Uniqueness of our Lord, and all the praises are for Him: O Allah, forgive me!")

Allah's Messenger (ﷺ) used to say very often in bowing and prostration (during his prayers), Subhanka Allahumma Rabbana wa bihamdika; Allahumma ighfirli," according to the order of the Qur'an.

`Umar asked the people regarding Allah's Statement: 'When comes the Help of Allah (to you O Muhammad against your enemies) and the conquest of Mecca.' (110.1) They replied, "It indicates the future conquest of towns and palaces (by Muslims)." `Umar said, "What do you say about it, O Ibn `Abbas?" I replied, "(This Surat) indicates the termination of the life of Muhammad. Through it he was informed of the nearness of his death."

`Umar used to make me sit with the elderly men who had fought in the Battle of Badr. Some of them felt it (did not like that) and said to `Umar "Why do you bring in this boy to sit with us while we have sons like him?" `Umar replied, "Because of what you know of his position (i.e. his religious knowledge.)" One day `Umar called me and made me sit in the gathering of those people; and I think that he called me just to show them. (my religious knowledge). `Umar then asked them (in my presence). "What do you say about the interpretation of the Statement of Allah: 'When comes Help of Allah (to you O, Muhammad against your enemies) and the conquest (of Mecca).' (110.1) Some of them said, "We are ordered to praise Allah and ask for His forgiveness when Allah's Help and the conquest (of Mecca) comes to us." Some others kept quiet and did not say anything. On that, `Umar asked me, "Do you say the same, O Ibn `Abbas?" I replied, "No." He said, 'What do you say then?" I replied, "That is the sign of the death of Allah's Messenger (ﷺ) which Allah informed him of. Allah said:-- '(O Muhammad) When comes the Help of Allah (to you against your enemies) and the conquest (of Mecca) (which is the sign of your death). You should celebrate the praises of your Lord and ask for His Forgiveness, and He is the One Who accepts the repentance and forgives.' (110.3) On that `Umar said, "I do not know anything about it other than what you have said."

When the Verse:-- 'And warn your tribe of near kindred.' (26.214) was revealed. Allah's Messenger (ﷺ) went out, and when he had ascended As-Safa mountain, he shouted, "O Sabahah!" The people said, "Who is that?" "Then they gathered around him, whereupon he said, "Do you see? If I inform you that cavalrymen are proceeding up the side of this mountain, will you believe me?" They said, "We have never heard you telling a lie." Then he said, "I am a plain warner to you of a coming severe punishment." Abu Lahab said, "May you perish! You gathered us only for this reason? " Then Abu Lahab went away. So the "Surat:--ul--LAHAB" 'Perish the hands of Abu Lahab!' (111.1) was revealed.

The Prophet (ﷺ) went out towards Al-Batha' and ascended the mountain and shouted, "O Sabahah!" So the Quraish people gathered around him. He said, "Do you see? If I tell you that an enemy is going to attack you in the morning or in the evening, will you believe me?" They replied, "Yes." He said, "Then I am a plain warner to you of a coming severe punishment." Abu Lahab said, "Is it for this reason that you have gathered us? May you perish ! " Then Allah revealed: 'Perish the hands of Abu Lahab!'

Abu Lahab said, "May you perish! Is it' for this that you have gathered us?" So there was revealed:'Perish the hands of Abu Lahab'.

The Prophet (ﷺ) said, "Allah said: 'The son of Adam tells a lie against Me,, though he hasn't the right to do so. He abuses me though he hasn't the right to do so. As for his telling a lie against Me, it is his saying that I will not recreate him as I created him for the first time. In fact, the first creation was not easier for Me than new creation. As for his abusing Me, it is his saying that Allah has begotten children, while I am the One, the Self-Sufficient Master Whom all creatures need, I beget not, nor was I begotten, and there is none like unto Me."

Allah's Messenger (ﷺ) said, "Allah said:-- 'The son of Adam tells a lie against Me and he hasn't the right to do so; and he abuses me and he hasn't the right to do so. His telling a lie against Me is his saying that I will not recreate him as I created him for the first time; and his abusing Me is his saying that Allah has begotten children, while I am the self-sufficient Master, Whom all creatures need, Who begets not nor was He begotten, and there is none like unto Me."

I asked Ubai bin Ka`b regarding the two Muwwidhat (Surats of taking refuge with Allah). He said, "I asked the Prophet (ﷺ) about them, He said, 'These two Surats have been recited to me and I have recited them (and are present in the Qur'an).' So, we say as Allah's Messenger (ﷺ) said (i.e., they are part of the Qur'an."

I asked Ubai bin Ka`b, "O Abu AlMundhir! Your brother, Ibn Mas`ud said so-and-so (i.e., the two Mu'awwidh-at do not belong to the Qur'an)." Ubai said, "I asked Allah's Messenger (ﷺ) about them, and he said, 'They have been revealed to me, and I have recited them (as a part of the Qur'an)," So Ubai added, "So we say as Allah's Messenger (ﷺ) has said."
