 After the Prophet ﷺ receives revelation and then he starts giving open da'wah after Allah ﷻ tells him وَاَنْ ذِرْ عَشِيرَةُ كَلْ أَقْرَبِينَ Go and warn your nearest family members. Basically, the Prophet ﷺ gets upon the mountain of Safa and he calls his closest family members, the closest tribes. By the way, when he comes to giving da'wah, a person has to set their home in order first and then worry about that of others. So the Prophet ﷺ gets his family together and starts giving them open da'wah. And we know how they reacted. He asked him ﷺ, if there's an army, if I said there's an army behind this mountain and they're coming to attack us, would you believe me? He said, of course, you're a Sadiq al-Ameen. We'll always believe you. You have never lied. The Prophet ﷺ said, I've come to warn you of something even greater and that is the date of judgment that is coming. And Abu Lahab gets furious at this and he picks up two rocks with his hands to throw them at the Prophet ﷺ. And he says that تَبَّ اللَّكَسَائِلَ الْأَيَامْ أَلِهَا دَا جَمَعْتَنَا May you be ruined for every day of your life. This is why you gathered us today. You're wasting our time with this. This is Abu Lahab. Again, the uncle of the Prophet ﷺ, he is saying this to him ﷺ. And at this, Allah ﷻ reveals the ayah that both hands of Abu Lahab may they be cursed. May he be cursed into the Hellfire. From then on, he was called Abu Lahab.
