"The seal thereof is musk" [83:26]. Mujahid said: The final drop is sealed with it.
Muhammad said: This means that when they drink this nectar, and what is in the cup is finished and the drinking ends, that finish is sealed with the taste and scent of musk.
He said: "And for this let the competitors compete" [83:26] in this world through righteous deeds.
﴿ختامه مسك﴾ قَالَ مُجَاهِدٌ: يُخْتَمُ بِهِ آخِرُ جَرْعَةٍ.
قَالَ مُحَمَّدٌ: يَعْنِي: أَنَّهُمْ إِذا شربوا هَذَا الرَّحِيق فقني مَا فِي الْكَأْسِ وَانْقَطَعَ الشُّرْبُ، انْخَتَمَ ذَلِكَ بِطَعْمِ الْمِسْكِ وَرَائِحَتِهِ.
قَالَ: ﴿وَفِي ذَلِكَ فَلْيَتَنَافَسِ الْمُتَنَافِسُونَ﴾ فِي الدُّنْيَا بِالْأَعْمَالِ الصَّالِحَة
