Musannaf Ibn Abi Shaybah

Hazrat Ibn Abbas (may Allah be pleased with them both) narrates that the Holy Prophet ﷺ sent an army towards Mu'tah and appointed Hazrat Zaid (may Allah be pleased with him) as the commander over them. He instructed that if Zaid (may Allah be pleased with him) is martyred, then Ja'far (may Allah be pleased with him) should be made the leader, and if Ja'far is also martyred, then Abdullah bin Rawahah should be made the leader. Despite the army's departure, Hazrat Abdullah bin Rawahah (may Allah be pleased with him) stayed behind with the intention of offering Jumu'ah (Friday prayer) with the Prophet ﷺ. When the Messenger of Allah ﷺ saw him, he asked, "Why did you stay behind?" He replied, "With the intention of offering Jumu'ah with you." The Prophet ﷺ said, "Spending a morning or an evening in the path of Allah is better than the world and whatever is in it."
