Abu Musa Ashari reported,

I went out with the Prophet ﷺ and he entered an orchard belonging to the Ansar, where he relieved himself. He said to me, "Abu Musa, guard the gate for me, and do not let anyone enter without permission."Then a man came and knocked at the gate.I asked, "Who is this?"He replied, "Abu Bakr."I said, "Messenger of Allah, this is Abu Bakr seeking permission to enter."He said, "Let him in, and give him the glad tidings of Paradise."So he entered, and I gave him the glad tidings of Paradise.Then another man came and knocked at the gate.I asked, "Who is this?"He replied, "Umar."I said, "Messenger of Allah, this is Umar seeking permission to enter."He said, "Open the gate for him, and give him the glad tidings of Paradise."So I opened the gate, he entered, and I gave him the glad tidings of Paradise.Then another man came and knocked at the gate.I asked, "Who is this?"He replied, "Uthman."I said, "Messenger of Allah, this is Uthman seeking permission to enter."He said, "Open the gate for him, and give him the glad tidings of Paradise, along with a trial that will befall him."
