The Night Journey
مَّن كَانَ يُرِيدُ ٱلْعَاجِلَةَ عَجَّلْنَا لَهُۥ فِيهَا مَا نَشَآءُ لِمَن نُّرِيدُ ثُمَّ جَعَلْنَا لَهُۥ جَهَنَّمَ يَصْلَىٰهَا مَذْمُومًا مَّدْحُورًا
Whoever should desire the immediate - We hasten for him from it what We will to whom We intend. Then We have made for him Hell, which he will [enter to] burn, censured and banished.
Nearby ayahs help place verse 17:18 in sequence and meaning.
وَإِذَآ أَرَدْنَآ أَن نُّهْلِكَ قَرْيَةً أَمَرْنَا مُتْرَفِيهَا فَفَسَقُوا۟ فِيهَا فَحَقَّ عَلَيْهَا ٱلْقَوْلُ فَدَمَّرْنَـٰهَا تَدْمِيرًا
And when We intend to destroy a city, We command its affluent but they defiantly disobey therein; so the word comes into effect upon it, and We destroy it with [complete] destruction.
وَكَمْ أَهْلَكْنَا مِنَ ٱلْقُرُونِ مِنۢ بَعْدِ نُوحٍ ۗ وَكَفَىٰ بِرَبِّكَ بِذُنُوبِ عِبَادِهِۦ خَبِيرًۢا بَصِيرًا
And how many have We destroyed from the generations after Noah. And sufficient is your Lord, concerning the sins of His servants, as Acquainted and Seeing.
وَمَنْ أَرَادَ ٱلْـَٔاخِرَةَ وَسَعَىٰ لَهَا سَعْيَهَا وَهُوَ مُؤْمِنٌ فَأُو۟لَـٰٓئِكَ كَانَ سَعْيُهُم مَّشْكُورًا
But whoever desires the Hereafter and exerts the effort due to it while he is a believer - it is those whose effort is ever appreciated [by Allah].
كُلًّا نُّمِدُّ هَـٰٓؤُلَآءِ وَهَـٰٓؤُلَآءِ مِنْ عَطَآءِ رَبِّكَ ۚ وَمَا كَانَ عَطَآءُ رَبِّكَ مَحْظُورًا
To each [category] We extend - to these and to those - from the gift of your Lord. And never has the gift of your Lord been restricted.
