Sahih al-Bukhari 7231
Narrated Aisha:
One night the Prophet was unable to sleep and said, "Would that a righteous man from my companions guarded me tonight." Suddenly we heard the clatter of arms, whereupon the Prophet ﷺ said, "Who is it?" It was said, "I am Sa'd, O Allah's Apostle! I have come to guard you." The Prophet then slept so soundly that we heard him snoring. Abu 'Abdullah said: 'Aisha said: Bilal said, "Would that I but stayed overnight in a valley with Idhkhir and Jalil (two kinds of grass) around me (i.e., in Mecca)." Then I told that to the Prophet .
حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ، حَدَّثَنَا سُلَيْمَانُ بْنُ بِلاَلٍ، حَدَّثَنِي يَحْيَى بْنُ سَعِيدٍ، سَمِعْتُ عَبْدَ اللَّهِ بْنَ عَامِرِ بْنِ رَبِيعَةَ، قَالَ قَالَتْ عَائِشَةُ أَرِقَ النَّبِيُّ ﷺ ذَاتَ لَيْلَةٍ فَقَالَ " لَيْتَ رَجُلاً صَالِحًا مِنْ أَصْحَابِي يَحْرُسُنِي اللَّيْلَةَ ". إِذْ سَمِعْنَا صَوْتَ السِّلاَحِ قَالَ " مَنْ هَذَا ". قِيلَ سَعْدٌ يَا رَسُولَ اللَّهِ جِئْتُ أَحْرُسُكَ. فَنَامَ النَّبِيُّ ﷺ حَتَّى سَمِعْنَا غَطِيطَهُ. قَالَ أَبُو عَبْدِ اللَّهِ وَقَالَتْ عَائِشَةُ قَالَ بِلاَلٌ أَلاَ لَيْتَ شِعْرِي هَلْ أَبِيتَنَّ لَيْلَةً بِوَادٍ وَحَوْلِي إِذْخِرٌ وَجَلِيلُ فَأَخْبَرْتُ النَّبِيَّ ﷺ.
