The Night Journey
أَقِمِ ٱلصَّلَوٰةَ لِدُلُوكِ ٱلشَّمْسِ إِلَىٰ غَسَقِ ٱلَّيْلِ وَقُرْءَانَ ٱلْفَجْرِ ۖ إِنَّ قُرْءَانَ ٱلْفَجْرِ كَانَ مَشْهُودًا
Establish prayer at the decline of the sun [from its meridian] until the darkness of the night and [also] the Qur'an of dawn. Indeed, the recitation of dawn is ever witnessed.
Nearby ayahs help place verse 17:78 in sequence and meaning.
وَإِن كَادُوا۟ لَيَسْتَفِزُّونَكَ مِنَ ٱلْأَرْضِ لِيُخْرِجُوكَ مِنْهَا ۖ وَإِذًا لَّا يَلْبَثُونَ خِلَـٰفَكَ إِلَّا قَلِيلًا
And indeed, they were about to drive you from the land to evict you therefrom. And then [when they do], they will not remain [there] after you, except for a little.
سُنَّةَ مَن قَدْ أَرْسَلْنَا قَبْلَكَ مِن رُّسُلِنَا ۖ وَلَا تَجِدُ لِسُنَّتِنَا تَحْوِيلًا
[That is Our] established way for those We had sent before you of Our messengers; and you will not find in Our way any alteration.
وَمِنَ ٱلَّيْلِ فَتَهَجَّدْ بِهِۦ نَافِلَةً لَّكَ عَسَىٰٓ أَن يَبْعَثَكَ رَبُّكَ مَقَامًا مَّحْمُودًا
And from [part of] the night, pray with it as additional [worship] for you; it is expected that your Lord will resurrect you to a praised station.
وَقُل رَّبِّ أَدْخِلْنِى مُدْخَلَ صِدْقٍ وَأَخْرِجْنِى مُخْرَجَ صِدْقٍ وَٱجْعَل لِّى مِن لَّدُنكَ سُلْطَـٰنًا نَّصِيرًا
And say, "My Lord, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting authority."
