Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) narrates: On the occasion of the Battle of Tabuk, (it was the practice of the Prophet صلی اللہ علیہ وسلم that) when the sun had declined before his departure, he would perform the Zuhr and Asr prayers together. And if he departed before the sun had declined, he would delay the Zuhr prayer until he halted for the Asr prayer. Similarly, regarding the Maghrib prayer, if the sun set before his departure, the Prophet صلی اللہ علیہ وسلم would perform the Maghrib and Isha prayers together. And if he departed before the sun had set, he would delay the Maghrib prayer, then halt for the Isha prayer, and perform both prayers together.
