Is the testimony of one who was martyred in jihad accepted if he was in a state of ritual impurity (junub), had not performed ghusl, and was not among those who pray?

Prayer holds a great status in Islam; it is the second pillar and the foundation of the religion, and the first thing a servant will be questioned about on the Day of Judgment. Authentic hadiths have explicitly stated that abandoning prayer constitutes kufr (disbelief), such as the hadith (definition): "Between a man and kufr is the abandonment of prayer," and "The covenant between us and them is prayer; whoever abandons it has disbelieved." Imam Ahmad used this as evidence for the kufr of one who abandons prayer out of laziness, while the majority of scholars do not consider him a disbeliever. They interpret the hadiths of takfir (declaring someone a disbeliever) to refer to one who denies the obligation of prayer or deems its abandonment permissible, or that the intended kufr is a lesser form of disbelief, not major kufr. On both views, if someone who abandoned prayer repents sincerely and is killed in battle, and Muslims are in need of him, he is considered a shahid (martyr). For those who consider him a disbeliever, he re-enters Islam with his repentance. For the majority, he is considered disobedient but attains martyrdom due to the general statement of the Prophet, peace and blessings be upon him: "Whoever is killed in the way of Allah is a shahid."
