If I am killed for the cause of Allah, will my sins be forgiven?

The Messenger (may Allah's peace and blessings be upon him) stood up and addressed his Companions and told them about the high status of Jihad and that the most noble deeds are jihad for establishing Allah’s religion on this earth and having faith in Allah. A man asked if Allah would forgive his sins if he were to be killed in battle while attempting to establish the dominance of Allah’s religion. The Messenger (may Allah's peace and blessings be upon him) replied in the positive.

However, there are conditions. One must be killed while being patient withstanding the pain, sincere in his cause, and without retreating. The Messenger (may Allah's peace and blessings be upon him) exempted debt, declaring that martyrdom is not an exemption to returning people their rights.
