Their sides forsake their beds (32:16) - "It was revealed about waiting for [this] Salat which you call Al-'Atamah."  

أَنَّ هَذِهِ الآيَةَ ( تتَجَافَى جُنُوبُهُمْ عَنِ الْمَضَاجِعِ ) نَزَلَتْ فِي انْتِظَارِ هَذِهِ الصَّلاَةِ الَّتِي تُدْعَى الْعَتَمَةَ  

that the Prophet ﷺ said: "Allah Most High said: 'I have prepared for My righteous worshipers what no eye has seen, no ear has heard, and no human heart has conceived.'" And that is testified to in Allah's [the Mighty and Sublime] Book: No person knows what is kept hidden for them of delights of the eyes (32:17).  

النَّبِيَّ ﷺ قَالَ قَالَ اللَّهُ تَعَالَى أَعْدَدْتُ لِعِبَادِي الصَّالِحِينَ مَا لاَ عَيْنٌ رَأَتْ وَلاَ أُذُنٌ سَمِعَتْ وَلاَ خَطَرَ عَلَى قَلْبِ بَشَرٍ وَتَصْدِيقُ ذَلِكَ فِي كِتَابِ اللَّهِ ﷻ ( فلاَ تَعْلَمُ نَفْسٌ مَا أُخْفِيَ لَهُمْ مِنْ قُرَّةِ أَعْيُنٍ جَزَاءً بِمَا كَانُوا يَعْمَلُونَ ) قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ  

"While he was on the Minbar, I heard Al-Mughirah bin Shu'bah saying - and he attributed it to the Prophet ﷺ - 'Indeed Musa [peace be upon him] asked his Lord: "O Lord! Who is the lowest in rank among the people of Paradise?" He said: "A man who comes after the people of Paradise have been admitted to Paradise, and he is told to enter. He says: 'How can I enter when they have gotten all of their abodes, and all that is to be had?'" He said: "So it is said to him: 'Would you accept if you were to have what a king in the world?' He says: 'Yes, O Lord! I accept.' So it is said to him: 'Then for you is this and its like, and its like again, and its like again.' So he says: 'I accept, O Lord!' So it is said to him: 'Then for you is this and ten the like thereof.' So he says: 'I accept, O Lord!' So it is said: 'Indeed you shall have this, and whatever your soul desires, and whatever delights your eyes.'"
