[Machine] The Prophet ﷺ used to stay up at night when he first arrived in Medina and said, "I wish a righteous man from my companions would guard me tonight." While we were in that state, we heard the sound of weapons. The Messenger of Allah ﷺ said, "Who is this?" Saad said, "It is I, Saad. I have come to guard you." The Messenger of Allah ﷺ said, "Let the Messenger of Allah rest."
كَانَ رَسُولُ اللهِ ﷺ فِي أَوَّلِ مَا قَدِمَ الْمَدِينَةَ يَسْهَرُ مِنَ اللَّيْلِ فَقَالَ «لَيْتَ رَجُلًا صَالِحًا مِنْ أَصْحَابِي يَحْرُسُنِي اللَّيْلَةَ» فَبَيْنَا نَحْنُ كَذَلِكَ إِذْ سَمِعْنَا صَوْتَ السِّلَاحِ قَالَ رَسُولُ اللهِ ﷺ «مَنْ هَذَا؟» قَالَ أَنَا سَعْدٌ جِئْتُ أَحْرُسُكَ قَالَتْ «وَنَامَ رَسُولُ اللهِ ﷺ»
