Hazm bin Abi Ka'b (may Allah be pleased with him) says that he came to Mu'adh (may Allah be pleased with him) while he was leading his people in the Maghrib prayer. In this narration it is mentioned that the Messenger of Allah (peace and blessings be upon him) said: "O Mu'adh! Do not be one who puts people to trial, for behind you pray the old, the weak, the needy or those with work, and the traveller."
The earlier narrations, which mention the Isha prayer, are more authentic, and Allah knows best.
