What was narrated concerning the believer being rewarded for the agony of death

It was narrated from ‘Aishah that the Messenger of Allah ﷺ entered upon her and there was a close relative of hers who was in the throes of death. When the Prophet ﷺ saw how upset she was, he said:
“Do not grieve for your relative, for that is part of his Hasanat (merits).”

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنَا الأَوْزَاعِيُّ، عَنْ عَطَاءٍ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ دَخَلَ عَلَيْهَا وَعِنْدَهَا حَمِيمٌ لَهَا يَخْنُقُهُ الْمَوْتُ فَلَمَّا رَأَى النَّبِيُّ ﷺ مَا بِهَا قَالَ لَهَا " لاَ تَبْتَئِسِي عَلَى حَمِيمِكِ فَإِنَّ ذَلِكَ مِنْ حَسَنَاتِهِ " .

It was narrated from Abu Buraidah from his father that the Prophet ﷺ said:
“The believer dies with sweat on his brow.”

حَدَّثَنَا بَكْرُ بْنُ خَلَفٍ أَبُو بِشْرٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنِ الْمُثَنَّى بْنِ سَعِيدٍ، عَنْ قَتَادَةَ، عَنِ ابْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، أَنَّ النَّبِيَّ ﷺ قَالَ " الْمُؤْمِنُ يَمُوتُ بِعَرَقِ الْجَبِينِ " .
