Nasai

´It was narrated from Salman Al-Khair that the Messenger of Allah (ﷺ) said:` "Whoever guards Ribat (the frontier) for one day and one night, will be given a reward like that for fasting and praying Qiyam for a month, and whoever dies at Ribat (guarding the frontier) will be rewarded, and he will be given provision, and he will be kept safe from Al-Fattan." [1] [1] According to As-Sindi, the preferred pronunciation is Al-Fattan, plural of Fatan refering to Al-Munkar and An-Nakir, while Al-Fattan would refer to Ash-Shaitan or the like, among the punishment of the grave, or, the angels of chastisement.

´It was narrated that Salman said:` "I heard the Messenger of Allah (ﷺ) say: 'Whoever guards Ribat (the frontier) in the cause of Allah for one day and one night, he will have (a reward) like that of fasting and praying Qiyam for a month. If he dies he will continue to receive reward for what he did, and he will be kept safe from Al-Fattan, and he will be given provision.'"

´It was narrated from Zurah bin Ma'bad:` "Abu Salih, the freed slave of 'Uthman, said: 'I heard 'Uthman bin 'Affan say: I heard the Messenger of Allah (ﷺ) say: Ribat (guarding the frontier) for one day in the cause of Allah is better in rank than a thousand days spent within the residence.'"

´It was narrated that Abu Salih, the freed slace of 'Uthman, said:` "uthman bin 'Affan said: 'I heard the Messenger of Allah (ﷺ) say: A day in the cause of Allah is better than a thousand days doing anything else.'"
