Hadith: Paradise is guaranteed for any Muslim who fights in the cause of Allah for the length of time between two milkings of a she-camel. Anyone is wounded or injured in the cause of Allah, it will come on the Day of Judgment bleeding the most it ever bled, but its color will be like saffron and its fragrance will be like musk

عن معاذ رضي الله عنه عن النبي صلى الله عليه وسلم قال: «مَنْ قاتل في سَبِيل الله من رَجُل مُسْلم فُوَاقَ نَاقَة، وجَبَتْ له الجنة، ومن جُرح جُرْحًا في سَبِيل الله أو نُكِبَ نَكْبَةً فإنها تَجِيء يوم القيامة كَأَغزَرِ ما كانت: لونُها الزَّعْفَرَانُ، وريُحها كالمِسك».
[صحيح] - [رواه أبو داود وأحمد والترمذي والنسائي وابن ماجه والدارمي]

Mu‘ādh (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Paradise is guaranteed for any Muslim who fights in the cause of Allah for the length of time between two milkings of a she-camel. Anyone is wounded or injured in the cause of Allah, it will come on the Day of Judgment bleeding the most it ever bled, but its color will be like saffron and its fragrance will be like musk."
[Authentic hadith] - [Narrated by Ibn Majah - Narrated by At-Termedhy - An-Nasaa’i - Narrated by Abu Daoud - Narrated by Ahmad - Ad-Daarimi]

Explanation

Paradise will be guaranteed for any Muslim who fights in the cause of Allah, even if only for a short while, such as the time duration between two consecutive turns of milking. This period is as short as it allows the she-camel to be milked, then left so that her calf can feed, and then returned to be milked another time. Anyone is injured in the cause of Allah, the Almighty, such as the injury from falling from his horse or from a sword, etc., even if it is a minor injury, he will come on the Day of Judgment with his wound bleeding profusely, except that the blood color will be that of saffron and the loveliest scent of musk will be released from it.
