It was narrated from 'Abdullah bin Abi Qatadah that his father said:

"We were with the Messenger of Allah ﷺ when some of the people said: 'Why do you not stop with us to rest awhile, 0 Messenger of Allah ﷺ?' He said: 'I am afraid that you will sleep and miss the prayer.' Bilal said:'I will wake you up.' So they lay down and slept, and Bilal leaned back on his mount. Then the Messenger of Allah ﷺ woke up when the sun had already started to rise, and he said: '0 Bilal, what about what you told us?' He said: 'I
have never slept like that before.' The Messenger of Allah ﷺ said: 'Allah, the Mighty and Sublime, takes your souls when He wills and sends them back when He wills.' Stand up 0 Bilal and call the people to prayer.' Then Bilal stood up and & called the Adhan, and they performed Wudu' - that is, when the sun had risen (fully) - "then he stood and lead them in prayer."

أَخْبَرَنَا هَنَّادُ بْنُ السَّرِيِّ، قَالَ حَدَّثَنَا أَبُو زُبَيْدٍ، - وَاسْمُهُ عَبْثَرُ بْنُ الْقَاسِمِ - عَنْ حُصَيْنٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ، عَنْ أَبِيهِ، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ إِذْ قَالَ بَعْضُ الْقَوْمِ لَوْ عَرَّسْتَ بِنَا يَا رَسُولَ اللَّهِ . قَالَ " إِنِّي أَخَافُ أَنْ تَنَامُوا عَنِ الصَّلاَةِ " . قَالَ بِلاَلٌ أَنَا أَحْفَظُكُمْ . فَاضْطَجَعُوا فَنَامُوا وَأَسْنَدَ بِلاَلٌ ظَهْرَهُ إِلَى رَاحِلَتِهِ فَاسْتَيْقَظَ رَسُولُ اللَّهِ ﷺ وَقَدْ طَلَعَ حَاجِبُ الشَّمْسِ فَقَالَ " يَا بِلاَلُ أَيْنَ مَا قُلْتَ " . قَالَ مَا أُلْقِيَتْ عَلَىَّ نَوْمَةٌ مِثْلُهَا قَطُّ . قَالَ رَسُولُ اللَّهِ ﷺ " إِنَّ اللَّهَ عَزَّ وَجَلَّ قَبَضَ أَرْوَاحَكُمْ حِينَ شَاءَ فَرَدَّهَا حِينَ شَاءَ قُمْ يَا بِلاَلُ فَآذِنِ النَّاسَ بِالصَّلاَةِ " . فَقَامَ بِلاَلٌ فَأَذَّنَ فَتَوَضَّئُوا - يَعْنِي حِينَ ارْتَفَعَتِ الشَّمْسُ - ثُمَّ قَامَ فَصَلَّى بِهِمْ .
