I heard ʿUthman in Mina saying: O people, I shall tell you a hadeeth that I heard from the Messenger of Allah ﷺ . He said: ʿStanding guard on the border for one day for the sake of Allah is better than one thousand ordinary days, so let a man stand on guard at the border as much as he wants.” [ʿUthman] said; Have I conveyed [the message]? They said: Yes. He said: O Allah, bear witness.
أَنَّهُ حَدَّثَهُ قَالَسَمِعْتُ عُثْمَانَ يَقُولُ بِمِنًى يَا أَيُّهَا النَّاسُ إِنِّي أُحَدِّثُكُمْ حَدِيثًا سَمِعْتُهُ مِنْ رَسُولِ اللهِ ﷺ يَقُولُ رِبَاطُ يَوْمٍ فِي سَبِيلِ اللهِ أَفْضَلُ مِنْ أَلْفِ يَوْمٍ فِيمَا سِوَاهُ فَلْيُرَابِطِ امْرُؤٌ كَيْفَ شَاءَ هَلْ بَلَّغْتُ؟ قَالُوا نَعَمْ قَالَ اللهُمَّ اشْهَدْ
