Mishkat al-Masabih 1871

Abu al-Darda, may Allah be pleased with him, said: The Messenger of Allah ﷺ said, ‘The one who gives alms or emancipates a slave at the time of death is like one who gives gifts when he is well provided for.’ Ahmad, al-Nasa’i, al-Darimi, and al-Tirmidhi transmitted it; al-Tirmidhi authenticated it.
