Were there a pious person from amongst my Companions who should keep a watch for me durin. the night? She (A'isha) reported: We were in this state that we heard the clanging noise of arms. lie (the Holy Prophet) said: Who is it? He said: This is Sa'd b. Abi Waqqas. Messenger of Allah ﷺ said to him: What brings you here? Thereupon he said: I harboured fear (lest any harm should come to) Messenger of Allah ﷺ, so I came to serve as your sentinel. Messenger of Allah ﷺ invoked blessings upon him. He then slept. This hadith has been transmitted on the authority of Ibn Rumh with a slight variation of wording.  

سَهِرَ رَسُولُ اللَّهِ ﷺ مَقْدَمَهُ الْمَدِينَةَ لَيْلَةً فَقَالَ لَيْتَ رَجُلاً صَالِحًا مِنْ أَصْحَابِي يَحْرُسُنِي اللَّيْلَةَ قَالَتْ فَبَيْنَا نَحْنُ كَذَلِكَ سَمِعْنَا خَشْخَشَةَ سِلاَحٍ فَقَالَ مَنْ هَذَا قَالَ سَعْدُ بْنُ أَبِي وَقَّاصٍ فَقَالَ رَسُولُ اللَّهِ ﷺ مَا جَاءَ بِكَ قَالَ وَقَعَ فِي نَفْسِي خَوْفٌ عَلَى رَسُولِ اللَّهِ ﷺ فَجِئْتُ أَحْرُسُهُ فَدَعَا لَهُ رَسُولُ اللَّهِ ﷺ ثُمَّ نَامَ وَفِي رِوَايَةِ ابْنِ رُمْحٍ فَقُلْنَا مَنْ هَذَا  

[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»  

"The Messenger of Allah ﷺ did not sleep one night upon arriving in Al-Madinah. So he said: 'If only a righteous man would guard me tonight.'" She said: "So we were like that, when we heard the clanging of weapons. He said: 'Who is this?' So he said: 'Sa'd bin Abi Waqqas.' So the Messenger of Allah ﷺ said: 'What has brought you?' Sa'd said: 'Fear for the Messenger of Allah ﷺ came upon me, so I came to protect him.' So the Messenger of Allah ﷺ supplicated for him, then slept." (Using translation from Tirmidhī 3756)  

سَهِرَ رَسُولُ اللهِ ﷺ مَقْدِمَهُ الْمَدِينَةَ لَيْلَةً قَالَ «لَيْتَ رَجُلًا صَالِحًا مِنْ أَصْحَابِي يَحْرُسُنِي اللَّيْلَةَ» قَالَ «فَبَيْنَا نَحْنُ كَذَلِكَ إِذْ سَمِعْنَا خَشْخَشَةَ سِلَاحٍ» فَقَالَ «مَنْ هَذَا؟» قَالَ سَعْدُ بْنُ أَبِي وَقَّاصٍ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ «مَا جَاءَ بِكَ؟» قَالَ سَعْدٌ «وَقَعَ فِي نَفْسِي خَوْفٌ عَلَى رَسُولِ اللهِ ﷺ فَجِئْتُ أَحْرُسُهُ فَدَعَا لَهُ رَسُولُ اللهِ ﷺ ثُمَّ نَامَ»
