[Machine] The sudden death is a relief for the believer and grief for the disbeliever.  

الطبراني:٨٨٦٥حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ أَنَا عَبْدُ الرَّزَّاقِ أَنَا مَعْمَرٌ عَنِ الْأَعْمَشِ عَنْ رَجُلٍ عَنْ أَبِي الْأَحْوَصِ عَنِ ابْنِ مَسْعُودٍ قَالَ

«مَوْتُ الْفَجْأَةِ تَخْفِيفٌ عَلَى الْمُؤْمِنِ وَأَسَفٌ عَلَى الْكَافِرِ»
