Narrated AbuHurayrah:

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

حَدَّثَنَا أَبُو تَوْبَةَ، : الرَّبِيعُ بْنُ نَافِعٍ عَنِ ابْنِ الْمُبَارَكِ، عَنِ ابْنِ أَبِي ذِئْبٍ، عَنِ الْقَاسِمِ، عَنْ بُكَيْرِ بْنِ عَبْدِ اللَّهِ بْنِ الأَشَجِّ، عَنِ ابْنِ مِكْرَزٍ، - رَجُلٍ مِنْ أَهْلِ الشَّامِ - عَنْ أَبِي هُرَيْرَةَ، : أَنَّ رَجُلاً، قَالَ : يَا رَسُولَ اللَّهِ، رَجُلٌ يُرِيدُ الْجِهَادَ فِي سَبِيلِ اللَّهِ وَهُوَ يَبْتَغِي عَرَضًا مِنْ عَرَضِ الدُّنْيَا فَقَالَ رَسُولُ اللَّهِ ﷺ : " لاَ أَجْرَ لَهُ " . فَأَعْظَمَ ذَلِكَ النَّاسُ، وَقَالُوا لِلرَّجُلِ : عُدْ لِرَسُولِ اللَّهِ ﷺ فَلَعَلَّكَ لَمْ تُفَهِّمْهُ . فَقَالَ : يَا رَسُولَ اللَّهِ، رَجُلٌ يُرِيدُ الْجِهَادَ فِي سَبِيلِ اللَّهِ وَهُوَ يَبْتَغِي عَرَضًا مِنْ عَرَضِ الدُّنْيَا . فَقَالَ : " لاَ أَجْرَ لَهُ " . فَقَالُوا لِلرَّجُلِ : عُدْ لِرَسُولِ اللَّهِ ﷺ . فَقَالَ لَهُ الثَّالِثَةَ، فَقَالَ لَهُ : " لاَ أَجْرَ لَهُ " .
