That the Messenger of Allah ﷺ said: "The martyr does not sense the touch of death except as one of you senses the touch of a (bug) bite.  

قَالَ رَسُولُ اللَّهِ ﷺ مَا يَجِدُ الشَّهِيدُ مِنْ مَسِّ الْقَتْلِ إِلاَّ كَمَا يَجِدُ أَحَدُكُمْ مِنْ مَسِّ الْقَرْصَةِ  

That the Prophet ﷺ said: "There is nothing more beloved to Allah than two drops and two traces: A teardrop shed out of fear of Allah, and a drop of blood shed in Allah's cause. As for the two traces: A trace resulting in Allah's cause, and and a trace resulting from one of the duties that Allah made obligatory."  

عَنِ النَّبِيِّ ﷺ قَالَ لَيْسَ شَيْءٌ أَحَبَّ إِلَى اللَّهِ مِنْ قَطْرَتَيْنِ وَأَثَرَيْنِ قَطْرَةٌ مِنْ دُمُوعٍ فِي خَشْيَةِ اللَّهِ وَقَطْرَةُ دَمٍ تُهَرَاقُ فِي سَبِيلِ اللَّهِ وَأَمَّا الأَثَرَانِ فَأَثَرٌ فِي سَبِيلِ اللَّهِ وَأَثَرٌ فِي فَرِيضَةٍ مِنْ فَرَائِضِ اللَّهِ قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ
