Fadala bin Ubaid (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The deeds of every deceased person are cut off except for the one who dies guarding the frontier in the way of Allah; his deeds will continue to increase until the Day of Resurrection, and he will be safe from the trial of the grave. I also heard the Messenger of Allah (peace and blessings of Allah be upon him) say: The true Mujahid is the one who strives against his own self." 1. Imam Tirmidhi says:
1- The hadith of Fadala is Hasan Sahih,
2- In this chapter, there are also ahadith from Uqbah bin Amir and Jabir (may Allah be pleased with them both).
