Mentioning some of the rulings concerning the martyr in battle.

The Shaykh : He said, "So we did not find anything to shroud him in except a cloak." In this hadith, there is an indication that martyrs, even though they are not washed and even though they are generally not prayed over, there is a distinction between these two rulings based on what is established in the Sunnah. The martyr in battle is not washed, but he is not prayed over unless it becomes easy for some Muslims to pray over him. Praying over him is permissible, but the difference between this martyr and other Muslim deceased is that the funeral prayer is not obligatory for the martyr; it is possible to bury him without a prayer absolutely. However, this does not mean that praying the funeral prayer over him is not permissible, nor does it mean that praying the funeral prayer over him is an innovation. If it had not been established in the Sunnah that the Prophet (peace and blessings be upon him) prayed over some of the martyrs, if this had not been established, then praying over the martyr would have been an innovation in Islam, because it would be one of the newly invented matters. But since it is established from the authentic Sunnah that the Messenger (may Allah's prayers and peace be upon him) sometimes prayed over some of the martyrs, his prayer indicated the permissibility of praying over the martyr, but only sometimes. The general case, which is what the circumstances of battles require, is that it is not possible to pray over this martyr. Perhaps if they waited for him, some corruption might spread to his body. The Sunnah is to hasten to bury him. As for washing him, it is certain that it is not prescribed. It is not like the prayer, where he is sometimes washed and sometimes not washed. Rather, the ruling in that is that he is not washed absolutely, and he is buried in the clothes in which he died. But in this hadith and others, it is explained that the meaning of the martyr being buried in the clothes in which he was killed does not mean that shrouding him is not from the Sunnah. Rather, he is shrouded over the clothes in which he died and buried with this shroud, applying this Sunnah. When they wanted to bury Mus'ab ibn 'Umar (may Allah be pleased with him), they did not find a cloak for him except a short cloak that did not cover his entire body. So, as you heard from Khubayb, when they covered his head with it, his feet would stick out, and when they covered his feet, his head would stick out. So the Messenger (peace be upon him) provided them with a way out of that and ordered them.
