Mukhtasar Bukhari

Sayyiduna Malik bin Huwairith (may Allah be pleased with him) says that two persons came to the Prophet (peace and blessings of Allah be upon him) with the intention of traveling, so the Prophet (peace and blessings of Allah be upon him) said to them: "When you set out (and the time for prayer comes), then give the adhan, then say the iqamah, and after that, the elder among you should lead you in prayer."
