It was narrated that Ibn Mas'ood said:

I came to the Prophet (ﷺ) on the day of Badr and said: I have killed Abu Jahl. He said: By Allah besides Whom there is no other god? I said: By Allah besides Whom there is no other god. And he repeated it three times. He said: Allahu Akbar, praise be to Allah Who fulfilled His promise, granted victory to His slave and defeated the Confederates alone. Let us go, and you can show him to me." So we set out and came to him and he said: "This was the pharaoh of this nation.”
