The Prophet ﷺ said, "A wound which a Muslim receives in Allah's cause will appear on the Day of Resurrection as it was at the time of infliction; blood will be flowing from the wound and its color will be that of the blood but will smell like musk."  

عَنِ النَّبِيِّ ﷺ قَالَ كُلُّ كَلْمٍ يُكْلَمُهُ الْمُسْلِمُ فِي سَبِيلِ اللَّهِ يَكُونُ يَوْمَ الْقِيَامَةِ كَهَيْئَتِهَا إِذْ طُعِنَتْ تَفَجَّرُ دَمًا اللَّوْنُ لَوْنُ الدَّمِ وَالْعَرْفُ عَرْفُ الْمِسْكِ  

[Machine] "And the Messenger of Allah ﷺ said: Every word spoken by a Muslim in the way of Allah, and then it would be on the Day of Resurrection as its appearance when it was stabbed; it gushes out blood the color of blood, and the aroma is the aroma of musk. Abdullah bin Ahmad said: My father said: The aroma means the scent."  

وَقَالَ رَسُولُ اللهِ ﷺ كُلُّ كَلْمٍ يُكْلَمُهُ الْمُسْلِمُ فِي سَبِيلِ اللهِ ثُمَّ يَكُونُ يَوْمَ الْقِيَامَةِ كَهَيْئَتِهَا إِذَا طُعِنَتْ تَنْفَجِرُ دَمًا اللَّوْنُ لَوْنُ الدَّمِ وَالْعَرْفُ عَرْفُ الْمِسْكِ قَالَ عَبْدُ اللهِ بْنُ أَحْمَدَ قَالَ أَبِي يَعْنِي الْعَرْفَ الرِّيحَ  

The Prophet ﷺ said, "A wound which a Muslim receives in Allah's cause will appear on the Day of Resurrection as it was at the time of infliction; blood will be flowing from the wound and its color will be that of the blood but will smell like musk." (Using translation from Bukhārī 237)   

وقَالَ رَسُولُ اللهِ ﷺ كُلُّ كَلْمٍ يُكْلَمُهُ الْمُسْلِمُ فِي سَبِيلِ اللهِ يَكُونُ يَوْمَ الْقِيَامَةِ كَهَيْئَتِهَا إِذَا طُعِنَتْ تَفَجَّرُ دَمًا فَاللَّوْنُ لَوْنُ الدَّمِ وَالْعَرْفُ عَرْفُ الْمِسْكِ
