Give generously without expecting anything in return

This hadith speaks about the importance of giving charity and how one should not take it back once it has been given. Umar bin Al-Khattab was donating a horse in the way of Allah when he noticed that its new possessor was not treating it properly. He thought that he could buy it back at a cheap price since it had become weak and emaciated, but when he asked the Prophet Muhammad ﷺ about this, he said that one should not buy back their charity or get their donations returned as this is similar to a dog eating its own vomit. This hadith teaches us that we must be generous with our donations and give them away without expecting anything in return. We must also remember that whatever we give away will be rewarded by Allah and will never go to waste.
