Abu Dawud Book 8, Hadith Number 2510.

Chapter : Not known.

Narated By AbuHurayrah : A man said: Apostle of Allah, a man wishes to take part in jihad in Allah’s path desiring some worldly advantage? The Prophet (PBUH) said: He will have not reward. The people thought it terrible, and they said to the man: Go back to the Apostle of Allah (PBUH), for you might not have made him understand well. He, therefore, (went and again) asked: Apostle of Allah, a man wishes to take part in jihad in Allah’s path desiring some worldly advantage? He replied: There is no reward for him. They again said to the man: Return to the Apostle of Allah. He, therefore, said to him third time. He replied: There is no reward for him.
