Question : May Allah have mercy on the martyr, and may Allah grant the martyr wudu.
Answer : If his family are disbelievers who are our enemies. Yes. If he has Muslim sons and you said to me that they are Muslim. Yes, the issue of the ranks requires consideration. If a Muslim is killed in the ranks of the disbelievers, it is obligatory that blood money be paid to him. For this reason, the case of Hudhayfah falls under this category.
