Musnad Ahmad 433
It was narrated that ‘Abdullah bin az-Zubair said:
`Uthman bin `Affan (رضي الله عنه) said, speaking from his minbar I am going to tell you a hadeeth that I heard from the Messenger of Allah (ﷺ) , nothing kept me from telling it to you except the fact that I care for you, I heard the Messenger of Allah (ﷺ) say: `Standing guard for one night for the sake of Allah, may He be exalted, is better than a thousand nights spent in prayer and [a thousand] days spent fasting.”
حَدَّثَنَا رَوْحٌ، حَدَّثَنَا كَهْمَسٌ، عَنْ مُصْعَبِ بْنِ ثَابِتٍ، عَنِ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، قَالَ قَالَ عُثْمَانُ بْنُ عَفَّانَ رَضِيَ اللَّهُ عَنْهُ وَهُوَ يَخْطُبُ عَلَى مِنْبَرِهِ إِنِّي مُحَدِّثُكُمْ حَدِيثًا سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَا كَانَ يَمْنَعُنِي أَنْ أُحَدِّثَكُمْ إِلَّا الضِّنُّ عَلَيْكُمْ وَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ حَرَسُ لَيْلَةٍ فِي سَبِيلِ اللَّهِ تَعَالَى أَفْضَلُ مِنْ أَلْفِ لَيْلَةٍ يُقَامُ لَيْلُهَا وَيُصَامُ نَهَارُهَا‏.‏
