Surah Al-Mutaffifin(83:5)
Sahih al-Bukhari
Fighting for the Cause of Allah (Jihaad)
Chapter: If someone gives his horse for Allah's Cause and then he sees it being sold
Narrated Aslam:
I heard `Umar bin Al-Khattab saying, "I gave a horse to be ridden in Allah's Cause and the person who got it intended to sell it or neglected it. So, I wanted to buy it as I thought he would sell it cheap. I consulted the Prophet (ﷺ) who said, "Do not buy it even if for one Dirham, because he who takes back his gift is like a dog swallowing its vomit."
