"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.'" (Using translation from Nasāʾī 3169)
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «رِبَاطُ يَوْمٍ فِي سَبِيلِ اللهِ خَيْرٌ مِنْ أَلْفِ يَوْمٍ فِيمَا سِوَاهُ مِنَ الْمَنَازِلِ»
