Al-Rabi’ b. Khalid al-Dabbi said:I heard al-Hajjaj say in his address: Is the messenger of one of you sent for some need is more respectable with him or his successor among his people? I thought in my mind: I make a vow for Allah that I shall never pray behind you. If I find people who fight against you, I shall fight against you along with them. Ishaq added in his version: He fought in the battle of al-Jamajim until he was killed
