Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: I asked the Messenger of Allah (peace and blessings be upon him); I said: "Some Muslim horsemen fell upon a people of the polytheists and fought them, and their children were also killed (in the process)." The Messenger of Allah (peace and blessings be upon him) said: "They are with their fathers."
