Abu Lahab was a bitter enemy of the prophet (PBH) inspite of being his uncle. When the prophet (PBH) had called his near relatives to invite them to Islam, Abu Lahab is reported to have cried out, “May you perish, have you called us for this.” Abu Lahab’s wife used to place thorns and sharp sticks in the path of prophet (PBH). This Sura is a curse against this couple.
