The Prophet (ﷺ) used to get up from his bed and recite the last ruku' of Surah Ali-Imran. [1]

إِنَّ فِي خَلْقِ السَّمَاوَاتِ وَالْأَرْضِ وَاخْتِلَافِ اللَّيْلِ وَالنَّهَارِ لَآيَاتٍ لِّأُولِي الْأَلْبَابِ ﴿١٩٠﴾ الَّذِينَ يَذْكُرُونَ اللَّـهَ قِيَامًا وَقُعُودًا وَعَلَىٰ جُنُوبِهِمْ وَيَتَفَكَّرُونَ فِي خَلْقِ السَّمَاوَاتِ وَالْأَرْضِ رَبَّنَا مَا خَلَقْتَ هَـٰذَا بَاطِلًا سُبْحَانَكَ فَقِنَا عَذَابَ النَّارِ ﴿١٩١﴾ رَبَّنَا إِنَّكَ مَن تُدْخِلِ النَّارَ فَقَدْ أَخْزَيْتَهُ ۖ وَمَا لِلظَّالِمِينَ مِنْ أَنصَارٍ ﴿١٩٢﴾ رَّبَّنَا إِنَّنَا سَمِعْنَا مُنَادِيًا يُنَادِي لِلْإِيمَانِ أَنْ آمِنُوا بِرَبِّكُمْ فَآمَنَّا ۚ رَبَّنَا فَاغْفِرْ لَنَا ذُنُوبَنَا وَكَفِّرْ عَنَّا سَيِّئَاتِنَا وَتَوَفَّنَا مَعَ الْأَبْرَارِ ﴿١٩٣﴾ رَبَّنَا وَآتِنَا مَا وَعَدتَّنَا عَلَىٰ رُسُلِكَ وَلَا تُخْزِنَا يَوْمَ الْقِيَامَةِ ۗ إِنَّكَ لَا تُخْلِفُ الْمِيعَادَ ﴿١٩٤﴾فَاسْتَجَابَ لَهُمْ رَبُّهُمْ أَنِّي لَا أُضِيعُ عَمَلَ عَامِلٍ مِّنكُم مِّن ذَكَرٍ أَوْ أُنثَىٰ ۖ بَعْضُكُم مِّن بَعْضٍ ۖ فَالَّذِينَ هَاجَرُوا وَأُخْرِجُوا مِن دِيَارِهِمْ وَأُوذُوا فِي سَبِيلِي وَقَاتَلُوا وَقُتِلُوا لَأُكَفِّرَنَّ عَنْهُمْ سَيِّئَاتِهِمْ وَلَأُدْخِلَنَّهُمْ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ ثَوَابًا مِّنْ عِندِ اللَّـهِ ۗ وَاللَّـهُ عِندَهُ حُسْنُ الثَّوَابِ ﴿١٩٥﴾ لَا يَغُرَّنَّكَ تَقَلُّبُ الَّذِينَ كَفَرُوا فِي الْبِلَادِ ﴿١٩٦﴾ مَتَاعٌ قَلِيلٌ ثُمَّ مَأْوَاهُمْ جَهَنَّمُ ۚ وَبِئْسَ الْمِهَادُ ﴿١٩٧﴾ لَـٰكِنِ الَّذِينَ اتَّقَوْا رَبَّهُمْ لَهُمْ جَنَّاتٌ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ خَالِدِينَ فِيهَا نُزُلًا مِّنْ عِندِ اللَّـهِ ۗ وَمَا عِندَ اللَّـهِ خَيْرٌ لِّلْأَبْرَارِ ﴿١٩٨﴾ وَإِنَّ مِنْ أَهْلِ الْكِتَابِ لَمَن يُؤْمِنُ بِاللَّـهِ وَمَا أُنزِلَ إِلَيْكُمْ وَمَا أُنزِلَ إِلَيْهِمْ خَاشِعِينَ لِلَّـهِ لَا يَشْتَرُونَ بِآيَاتِ اللَّـهِ ثَمَنًا قَلِيلًا ۗ أُولَـٰئِكَ لَهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ ۗ إِنَّ اللَّـهَ سَرِيعُ الْحِسَابِ ﴿١٩٩﴾ يَا أَيُّهَا الَّذِينَ آمَنُوا اصْبِرُوا وَصَابِرُوا وَرَابِطُوا وَاتَّقُوا اللَّـهَ لَعَلَّكُمْ تُفْلِحُونَ ﴿٢٠٠﴾

(190) Indeed, in the creation of the heavens and the earth and the alternation of the night and the day are signs for those of understanding. (191) Who remember Allah while standing or sitting or [lying] on their sides and give thought to the creation of the heavens and the earth, [saying], "Our Lord, You did not create this aimlessly; exalted are You [above such a thing]; then protect us from the punishment of the Fire. (192) Our Lord, indeed whoever You admit to the Fire - You have disgraced him, and for the wrongdoers there are no helpers. (193) Our Lord, indeed we have heard a caller calling to faith, [saying], 'Believe in your Lord,' and we have believed. Our Lord, so forgive us our sins and remove from us our misdeeds and cause us to die with the righteous. (194) Our Lord, and grant us what You promised us through Your messengers and do not disgrace us on the Day of Resurrection. Indeed, You do not fail in [Your] promise." (195) And their Lord responded to them, "Never will I allow to be lost the work of [any] worker among you, whether male or female; you are of one another. So those who emigrated or were evicted from their homes or were harmed in My cause or fought or were killed - I will surely remove from them their misdeeds, and I will surely admit them to gardens beneath which rivers flow as reward from Allah, and Allah has with Him the best reward." (196) Be not deceived by the [uninhibited] movement of the disbelievers throughout the land. (197) [It is but] a small enjoyment; then their [final] refuge is Hell, and wretched is the resting place. (198) But those who feared their Lord will have gardens beneath which rivers flow, abiding eternally therein, as accommodation from Allah . And that which is with Allah is best for the righteous. (199) And indeed, among the People of the Scripture are those who believe in Allah and what was revealed to you and what was revealed to them, [being] humbly submissive to Allah . They do not exchange the verses of Allah for a small price. Those will have their reward with their Lord. Indeed, Allah is swift in account. (200) O you who have believed, persevere and endure and remain stationed and fear Allah that you may be successful. (Surah Al-Imran 3:190-200) In another narration, The Prophet (ﷺ) used to get up from his bed and look at the sky and recite the first five verses of the last Ruku' of Surah Ali-Imran. [2]
