Sahih al-Bukhari Book 62, Hadith 42
When `Umar was stabbed, he showed signs of agony. Ibn `Abbas, as if intending to encourage `Umar,
said to him, "O Chief of the believers! Never mind what has happened to you, for you have been in
the company of Allah's Messenger (ﷺ) and you kept good relations with him and you parted with him while
he was pleased with you. Then you were in the company of Abu Bakr and kept good relations with
him and you parted with him (i.e. he died) while he was pleased with you. Then you were in the
company of the Muslims, and you kept good relations with them, and if you leave them, you will
leave them while they are pleased with you." `Umar said, (to Ibn "Abbas), "As for what you have said
about the company of Allah's Messenger (ﷺ) and his being pleased with me, it is a favor, Allah did to me;
and as for what you have said about the company of Abu Bakr and his being pleased with me, it is a
favor Allah did to me; and concerning my impatience which you see, is because of you and your
companions. By Allah! If (at all) I had gold equal to the earth, I would have ransomed myself with it
from the Punishment of Allah before I meet Him."
I heard Allah's Messenger (ﷺ) saying, "While I was sleeping, the people were presented to me (in a dream). They were wearing shirts, some of which were merely covering their (chests). and some were a bit longer. `Umar was presented before me and his shirt was so long that he was dragging it." They asked, "How have you interpreted it, O Allah's Messenger (ﷺ)?" He said, "Religion."
While I was with the Prophet (ﷺ) in one of the gardens of Medina, a man came and asked me to open the gate. The Prophet (ﷺ) said to me, "Open the gate for him and give him the glad tidings that he will enter Paradise." I opened (the gate) for him, and behold! It was Abu Bakr. I informed him of the glad tidings the Prophet (ﷺ) had said, and he praised Allah. Then another man came and asked me to open the gate. The Prophet (ﷺ) said to me "Open (the gate) and give him the glad tidings of entering Paradise." I opened (the gate) for him, and behold! It was `Umar. I informed him of what the Prophet (ﷺ) had said, and he praised Allah. Then another man came and asked me to open the gate. The Prophet (ﷺ) said to me. "Open (the gate) for him and inform him of the glad tidings, of entering Paradise with a calamity which will befall him. " Behold ! It was `Uthman, I informed him of what Allah's Messenger (ﷺ) had said. He praised Allah and said, "I seek Allah's Aid."
