Answer
In the name of Allah, we have mentioned in previous statements that the martyr has sacrificed his most precious thing, which is life for the sake of Allah. Additionally, there is a benefaction above another benefaction, and being killed for the path of Allah has no benefaction above it, but all goodness is in the sword and under its shadow. It was mentioned that the martyr who was killed for the sake of Allah (especially the one who breathes his last while he is in battle, he is buried with his blood-stained clothes to stand in the hands of Allah as he is) would rewarded with rewards that Allah has made for them, including:
1 . Allah is pleased with him, which is better and greater than heaven.
2. He would be covered with clothing from paradise.
3. His sins are forgiven when the first drop of blood sheds from him.
4. He sees his home in heaven.
5. His head falls in the hands of two wives from the hoor al-'iyn [heavenly wives], wiping dust off his face and telling him: Welcome to you, and he responds the same.
6. The treasury of Paradise shall initiate him with every good wind, whichever one he takes with him.
7. It is said to his soul to relax in paradise where it wants.
8 . Looking in the face of Allah. What is meant by looking in the face of Allah is to feel the sympathy of Allah for him and the amplification of His generosity (praise to Him). And it is a comfort for every prophet and martyr( and a satisfaction from Allah is greater)
This is some of what Allah has as the martyr did what he should do. As for what we must do, it is that we take care of his family and check on his orphans, so that we compensate them for losing their father and make them feel that we owe them and their father and not the opposite. Allah is the all Guide and Helper.
