The Prophet (ﷺ) said, "One who takes back his gift (which he has already given) is like a dog that swallows its vomit."
Sahih al-Bukhari Book 51, Hadith 23
← Previous Hadith Ubaidullah bin `Abdullah told me that `Aisha had said, "When the Prophet (ﷺ) became sick and his condition became serious, he requested his wives to allow him to be treated in my house, and they allowed him. He came out leaning on two men while his feet were dragging on the ground. He was walking between Al-`Abbas and another man." 'Ubaidullah said, "When I informed Ibn `Abbas of what `Aisha had said, he asked me whether I knew who was the second man whom `Aisha had not named. I replied in the negative. He said, 'He was `Ali bin Abi Talib."

The Prophet (ﷺ) said, "Give in charity and do not withhold it; otherwise Allah will withhold it back from you . "
