Jamiat Tirmidhi: Hadith 1764

That he heard is father, narating a Hadith, which he heard from the Messenger of Allah (ﷺ) in which he stood among them, mentioning to them that Jihad in the cause of Allah and faith in Allah were the most virtuous of deeds. Then a man stood and said: "O Messenger of Allah! If I were killed in the cause of Allah, would my sins forgiven ?" So the Messenger of Allah (ﷺ) said: "Yes, If you are killed in Allah's cause, and you are patient, seeking the reward, advancing, not fleeing." Then the Messenger of Allah (ﷺ) said: "What was it that you said?" So he replied: "If I were killed in the cause of Allah, would my sins be removed (forgiven)?" So the Messenger of Allah (ﷺ) said: "Yes, If you are patient, seeking the reward, advancing, not fleeing - except debt. For Jibril said that to me."

[Abu 'Eisa said:] There are narrations on this topic from Anas, Muhammad bin Jahsh, And Abu Hurairah. This Hadith is Hasan Sahih.

Some of them reported this Hadith from Sa'eed Al-Maqburi, from Abu Hurairah, from the Prophet (ﷺ) similar to this. Yahya bin Sa'eed Al-Ansari and more than one narrator reported this from Sa'eed Al-Maqburi from 'Abdullah bin Abi Qatadah, from his fahter, from the Prophet (ﷺ). This is more correct than the narration of Sa'eed Al-Maqburi from Abu Hurairah.
