Hadith 2885

Narrated `Aisha:

The Prophet was vigilant one night and when he reached Medina, he said, "Would that a pious man from my companions guard me tonight!" Suddenly we heard the clatter of arms. He said, "Who is that? " He (The new comer) replied, " I am Sa`d bin Abi Waqqas and have come to guard you." So, the Prophet slept (that night).

حَدَّثَنَا إِسْمَاعِيلُ بْنُ خَلِيلٍ، أَخْبَرَنَا عَلِيُّ بْنُ مُسْهِرٍ، أَخْبَرَنَا يَحْيَى بْنُ سَعِيدٍ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ عَامِرِ بْنِ رَبِيعَةَ، قَالَ سَمِعْتُ عَائِشَةَ ـ رضى الله عنها ـ تَقُولُ كَانَ النَّبِيُّ صلى الله عليه وسلم سَهِرَ فَلَمَّا قَدِمَ الْمَدِينَةَ قَالَ ‏"‏ لَيْتَ رَجُلاً مِنْ أَصْحَابِي صَالِحًا يَحْرُسُنِي اللَّيْلَةَ ‏"‏‏.‏ إِذْ سَمِعْنَا صَوْتَ سِلاَحٍ فَقَالَ ‏"‏ مَنْ هَذَا ‏"‏‏.‏ فَقَالَ أَنَا سَعْدُ بْنُ أَبِي وَقَّاصٍ، جِئْتُ لأَحْرُسَكَ‏.‏ وَنَامَ النَّبِيُّ صلى الله عليه وسلم‏.‏
