The Night Journey
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.

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.
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.
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."
وَقُلْ جَآءَ ٱلْحَقُّ وَزَهَقَ ٱلْبَـٰطِلُ ۚ إِنَّ ٱلْبَـٰطِلَ كَانَ زَهُوقًا
And say, "Truth has come, and falsehood has departed. Indeed is falsehood, [by nature], ever bound to depart."
