Tawus al-Yamani (may Allah have mercy on him) narrates from Sayyiduna Mu'adh (may Allah be pleased with him); he said that the Messenger of Allah (peace and blessings be upon him) said: "No human being has done any deed that saves him more from the punishment of Allah than the remembrance of Allah." The Companions said: "Not even jihad in the path of Allah?" He (peace and blessings be upon him) said: "Not even that, unless you strike with your sword until it breaks." He said this three times.
