"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.'"
Sunan an-Nasa'i Book 25, Hadith 85
← Previous Hadith "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.'"
