IBNHIBBAN 4623:
from Shuraḥbīl b. al-Simṭ —
Salman passed by ˹Shurahbil˺ while he was stationed for guarding and asked, "What are you doing here, Shurahabil?" Shurahabil replied, "I am performing ribat (guarding) in the cause of Allah." Salman said, "I heard the Messenger of Allah ﷺ say, 'The act of guarding for a day or a night is better than fasting and praying for an entire month.'"
ابن حبّان ٤٦٢٣:
عن شرحبيل بن السمط —
أَنَّهُ مَرَّ عَلَيْهِ سَلْمَانُ وَهُوَ مُرَابِطٌ فَقَالَ مَا تَصْنَعُ هَاهُنَا يَا شُرَحْبِيلُ؟ فَقَالَ شُرَحْبِيلُ أُرَابِطُ فِي سَبِيلِ اللَّهِ قَالَ سَلْمَانُ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «رِبَاطُ يَوْمٍ أَوْ لَيْلَةٍ خَيْرٌ مِنْ صِيَامِ شَهْرٍ وَقِيَامِهِ»
