Is he who wishes for martyrdom in order to enter Paradise considered insincere to Allah, and is fighting in the way of Allah in order to enter Paradise, defend the homeland, and support Al-Aqsa and the religion considered forbidden?

Wishing for martyrdom in the way of Allah is desirable. And whoever sincerely wishes for it, Allah will grant him the stations of martyrs, even if he dies on his bed, as the Prophet, peace and blessings be upon him, said: "Whoever sincerely asks Allah for martyrdom, Allah will make him reach the stations of the martyrs, even if he dies on his bed." Sincerity means intending the Face of Allah through one's worship and seeking Paradise and good reward; this does not contradict that. Defending Islam and fighting the occupier is a religious obligation, and whoever is killed while defending that is a martyr, for the saying of the Prophet, peace and blessings be upon him: "Whoever is killed defending his property is a martyr, and whoever is killed defending his family, or his blood, or his religion is a martyr."
