Abu Musa Ashari reported,

He was with the Prophet ﷺ in one of the gardens of Medina, and in the Prophet's ﷺ hand was a stick with which he was striking the mud and water. A man came seeking entry, and the Prophet ﷺ said, "Let him in, and give him the good news of Paradise."I went, and there was Abu Bakr, so I let him in and gave him the good news of Paradise.Then another man sought entry, and the Prophet said, "Let him in, and give him the good news of Paradise."It was Umar, so I let him in and gave him the good news of Paradise.Then another man sought entry. The Prophet had been reclining, but he sat up and said, "Let him in, and give him the good news of Paradise, along with a trial that will befall him."I went, and there was Uthman. I stood, let him in, and gave him the good news of Paradise, and I told him what the Prophet had said.Uthman replied, "Allah is the One whose help is sought."
