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.

← Previous Hadith `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."

Sahih al-Bukhari Book 65, Hadith 492 Next Hadith → 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!'
