"And of My slaves who goes out as a Mujahid striving in the cause of Allah, seeking my pleasure, I guarantee that I will bring him back with whatever he had earned as reward or spoils of war, and if I take his (soul) I will forgive him and have mercy on him."
Sunan an-Nasa'i Book 25, Hadith 42
← Previous Hadith "I heard the Messenger of Allah (ﷺ) say: 'There is no raiding party that goes out in the cause of Allah and acquires some spoils of war, but they have been given two-thirds of their reward in this world instead of in the Hereafter, and there remains one-third (in the Hereafter). And if they do not acquire any spoils of war, then all of their reward (will come in the Hereafter).'"

Sunan an-Nasa'i Book 25, Hadith 41 Next Hadith → "I heard the Messenger of Allah (ﷺ) say: 'The parable of a Mujahid who strives in the cause of Allah - and Allah knows best who in His cause - is that of one who fasts, prays Qiyam, focuses with proper humility, bows and prostrates.'"
