Ibn Abi Al-Dunya narrated the following, based on a chain of citations. NEbuchadnezzar captured two lions and threw them into a pit. He then brought Daniel and threw him at them; yet they did not pounce at him; rather, he remained as Allah wished. When then he desired food and drink, Allah revealed to Jeremiah, who was in Sham (Palestine/Syria): "Prepare food and drink for Daniel." He said: "0 Lord I am in Jerusalem while Daniel is in Babylon (Iraq)." Allah revealed to him: "Do what I have commanded you to do, and I shall send you one who will carry you and what you have prepared." Jeremiah did so and Allah sent him something that would carry him until he arrived at the brink of the pit.
Then Daniel asked: "Who is this?" He answered: "I am Jeremiah." He asked: "What brought you?" He answered: "Your Lord sent me to you." He said: "And so my Lord has remembered me?" He said: "Yes." Daniel said: "Praise be to Allah Who has never forgotten me! And Praise be to Allah Who never forgets those who appeal to Him! And Praise be to Him Who compensates good with good, rewards patience with safety, dispels harm after distress, assures us when we are overwhelmed, and is our hope when skill fails us."
Daniel's Death - Hadith
Abu Bakr Ibn Abu Dunya wrote in the book Ahkam-alQubur (The Rules of Graves), based on a long chain of citation, that the Prophet said: "Daniel prayed to his Lord, Great and Majestic for the nation of Muhammad to bury him." And he (i.e. Muhammad, PBUH) said: "Whoever discovers Daniel give him tidings of Paradise." The man who discovered him (his corpse) was called Harqus. Umar sent to Abu Musa saying: "Bury him; and send to Harqus, for the Prophet has given him promise of Paradise."
This hadith is mursal (it has a good chain of citation) as it is recorded, and Allah knows best.
