Musannaf Ibn Abi Shayba 33:631

Muhammad ibn Fudayl narrated to us, from Husayn, who said: Someone who heard al-Rabi’ narrated to me, saying: "How strange is the Angel of Death and his coming to three: A king who is fortified in his strongholds, so he comes to him and extracts his soul, leaving his kingdom behind him. And a skilled physician who treats people, so he comes to him and extracts his soul. And a destitute person, cast aside on the road, whom people find too repulsive to approach, yet the Angel of Death does not find it repulsive to come to him and extract his soul."
