Sharhabeel bin Simt narrates: Once, Sayyiduna Salman al-Farsi (may Allah be pleased with him) passed by him while he was performing guard duty. Sayyiduna Salman (may Allah be pleased with him) said: I heard the Prophet Muhammad (peace and blessings be upon him) say: "Whoever dies while standing guard, his deeds continue as before, and he is protected from the trials (of the grave), and he is provided sustenance (in the Hereafter)."
