[Abu Thar Jawad]

Al hamduliLah wa salat wa salam ala RassuliLah

Shaykh Uthaymeen rahimahu Allah said: the mujahid in Allah cause does not have a greater reward than the student of knowledge if he is killed in the battle field for the sake of Allah 'aza wa jal. He does not have the best reward. And this was pointed out by the scholar Ibn Qaym rahimahu Allah, that if a person specialised in a characteristic that does not mean he has the best reward.
The shaheed he characterized in the jihad for the sake of Allah.
But under the hand of the student of knowledge and the ulama is a maslaha (rectifying) the ummah and spreading the dawah that would not be in the shaheed account.
Have you not seen how much Shaykh al islam ibn Taymiya benefited the ummah?
If you took a big number of mujahideen you will not find what has been brought of benefit for
the ummah like the knowledge of shaykh al islam ibn Taymiya rahimahu Allah
over all of them.

Taken from the majmuu al fatawa of Shaykhna Saleh Ibn Uthaymine rahimahu Allah.
Fatwa number 25/ 306-307
