Sayyiduna Abu al-Tufayl Amir bin Wathilah narrates from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with them both) that it was reported to them that they went out with the Prophet (peace and blessings be upon him) on the expedition of Tabuk, and the Prophet (peace and blessings be upon him) combined Zuhr and Asr, and Maghrib and Isha. One day he delayed the prayer; then he (peace and blessings be upon him) came out and led Zuhr and Asr, then went inside, then came out again and led Maghrib and Isha together.
