It is narrated from Makharraq, he says: On the day of the Battle of Jamal, I met Sayyiduna Ammar (may Allah be pleased with him) while he was urinating in a horn. I said: I want to fight alongside you, and in this way, I will stay with you. But he said: You should fight while remaining under the flag of your own people, because the Messenger of Allah (peace and blessings be upon him) used to like that a man should fight while remaining under the flag of his own people.
