Musannaf Ibn Abi Shaybah 20646 — What is mentioned on the virtue

Al-Simt bin Abdullah said: Sayyiduna Salman (may Allah be pleased with him) was in an army of the Muslims. The Muslims faced a siege and hardship, so Sayyiduna Salman (may Allah be pleased with him) said to the commander of the army: "Let me tell you a saying of the Prophet (peace and blessings be upon him) that will be a help to you in the matter of this army. I heard the Prophet (peace and blessings be upon him) say: 'Whoever spends a day or a night in the path of Allah guarding the frontier, it is for him equal to a month in which he fasts continuously and prays continuously, leaving (his prayer) only for a need. And whoever dies while guarding the frontier in the path of Allah, its reward will continue to reach him until Allah Almighty has finished judging between the people of Paradise and the people of Hell.'"
