quran:83:26 –

The last of it is musk. So for this let the competitors compete.  

whose seal is musk, that is, whose final sip is followed by an emanating scent of musk — so for such ˹bliss˺ let the viers vie, let them desire to apply themselves to obedience of God —
القرآن:٨٣:٢٦ –

خِتَامُهُ مِسْكٌ ۚ وَفِي ذَٰلِكَ فَلْيَتَنَافَسِ الْمُتَنَافِسُونَ  

{ختامه مسك} أي آخر شربه تفوح من رائحة المسك {وفي ذلك فليتنافس المتنافسون} فليرغبوا بالمبادرة إلى طاعة الله.
