Qays bin Abi Hazim (may Allah have mercy on him) said: On the day of the Battle of Yarmuk I saw Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) shooting arrows between two targets, and with him were some men from among the Companions of the Prophet (peace and blessings be upon him). He said: "We have been commanded to teach our children archery and the Qur'an."
