It is narrated from Sayyiduna Salman al-Farisi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever guards the frontier (ribat) for a day and a night in the path of Allah will have the reward of fasting a month and standing its nights in prayer. And whoever dies while guarding the frontier (as a murabit), that deed of his will continue (until the Day of Resurrection), he will continue to be given provision, and he will be safe from the trial of the grave." This hadith has a sahih (authentic) chain, but the two Shaykhs did not record it.
