The Night Journey
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].

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.
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.
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.
ٱنظُرْ كَيْفَ فَضَّلْنَا بَعْضَهُمْ عَلَىٰ بَعْضٍ ۚ وَلَلْـَٔاخِرَةُ أَكْبَرُ دَرَجَـٰتٍ وَأَكْبَرُ تَفْضِيلًا
Look how We have favored [in provision] some of them over others. But the Hereafter is greater in degrees [of difference] and greater in distinction.
