Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: When this verse was revealed: "And warn your nearest kinsfolk" [Surah al-Shu'ara: 214], (meaning:) warn your close relatives, and also the sincere group among them who are with you (peace and blessings be upon him), the Messenger of Allah (peace and blessings be upon him) went out, climbed (the hill of) al-Safa and called out loudly: "Wa sabahah!" (The danger of the morning!) The people said: Who is this calling? (Some) said: Muhammad (peace and blessings be upon him). Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: All the people gathered around him (peace and blessings be upon him), and he (peace and blessings be upon him) said: "O Banu so-and-so! O Banu so-and-so! O Banu Abd Manaf! O Banu Abd al-Muttalib! What do you think: if I told you that an army is coming from the foot of this mountain, would you believe me?" They said: We have never found you lying. So he (peace and blessings be upon him) said: "Indeed I am a warner to you of a severe punishment that is coming." Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: Abu Lahab said: May you perish! Is it for this that you gathered us? Then he stood up, and Allah Almighty revealed this surah: "Perish the two hands of Abu Lahab, and perish he" [Surah al-Masad: 1]. Al-A'mash recited it in this way to the end of the surah.
