It was narrated from (Ibn Buraidah) that his father said:

"I heard the Messenger of Allah say: 'The believer dies with sweat on his forehead."'

أَخْبَرَنَا مُحَمَّدُ بْنُ مَعْمَرٍ، قَالَ حَدَّثَنَا يُوسُفُ بْنُ يَعْقُوبَ، قَالَ حَدَّثَنَا كَهْمَسٌ، عَنِ ابْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ " الْمُؤْمِنُ يَمُوتُ بِعَرَقِ الْجَبِينِ " .
