Narrated Ibn Abbas:
When the Verse:-- 'And warn your tribe of near kindred.' (26.214) was revealed. Allah's Apostle 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.
