It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Some people passed by Isa bin Maryam (peace be upon him), and he said: 'One of these will die today, if Allah wills.' They went on, then returned to him in the evening carrying bundles of firewood. He said: 'Put the bundles down.' Then he said to the man of whom he had said that he would die today: 'Untie your bundle.' He untied it, and in it was a black snake. He asked: 'What deed did you do today?' He said: 'I did not do any (particular) deed.' He said: 'Think about what you have done.' He said: 'I did nothing, except that I had a piece of bread in my hand, and a poor man passed by me and asked me, so I gave him some of it.' Then he said: 'Because of it this (calamity) was averted from you.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ata except Humayd, the freed slave of Alqamah; Zayd bin al-Hubab is alone in narrating it."
