Hadith 180

Sahih Bukhari

Book 56: Fighting for the Cause of Allah (Jihaad)

Chapter 119

The wages given to fight on somebody else's behalf

باب الْجَعَائِلِ وَالْحُمْلاَنِ فِي السَّبِيلِ

Mujahid said, "Once I said to Ibn 'Umar, 'Let us proceed for Jihad.' Ibn 'Umar replied, 'I would like to support you with some of my money.' I replied, 'Allah has given me enough.' He said, 'Your wealth is for you, but I like that some of my money be spent in this cause.'" 'Umar said, "Some people take money (from the Muslim’s Treasury) to strive in Allah’s Cause, but they don’t strive. So, if someone does so, we have the right to take back whatever he has taken." Tawus and Mujahid said, "If something is given to you, so that you may strive in Allah’s Cause, then do whatever you like with it and keep it with your family."
Sahih al-Bukhari 2971
حَدَّثَنَا إِسْمَاعِيلُ، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما أَنَّ عُمَرَ بْنَ الْخَطَّابِ، حَمَلَ عَلَى فَرَسٍ فِي سَبِيلِ اللَّهِ، فَوَجَدَهُ يُبَاعُ، فَأَرَادَ أَنْ يَبْتَاعَهُ، فَسَأَلَ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏ ‏‏.‏
"‏ لاَ تَبْتَعْهُ، وَلاَ تَعُدْ فِي صَدَقَتِكَ ‏"
`Abdullah bin `Umar:

`Umar gave a horse to be used in Allah's Cause, but later on he found it being sold. So, he intended to buy it and asked Allah's Messenger (ﷺ) who said, "Don't buy it and don't take back your gift of charity."
