Narrated Abu Mûsa Al-Ash'arî
I performed ablution in my house and then went out and said, "Today I shall stick to (or remain constantly with) Allâh's Messenger (ﷺ) and stay with him all this day of mine (in his service)." I went to the mosque and asked about the Prophet (ﷺ) They said, "He had gone in this direction." So I followed his way, asking about him till he entered a place called Bi'r Arîs. I sat at its gate that was made of date-palm leaves till the Prophet (ﷺ) finished answering the call of nature and performed ablution. Then I went up to him to see him sitting at the well of Arîs at the middle of its edge with his legs uncovered, hanging in the well. I greeted him and went back and sat at the gate. I said, Today I will be the gatekeeper of the Prophet (ﷺ) " Abu Bakr came and pushed the gate. ' I asked, "Who is it?" He said, Bakr." I told him to wait, went in and said, "O Allâh's Messenger (ﷺ)! Abu Bakr asks for permission to enter." He said, "Admit him and give him the glad tidings that he will be in Paradise." So I went out and said to Bakr, "Come in, and Allâh's Messenger (ﷺ) gives you the glad tidings that you will be in Paradise." Bakr entered and sat on the right side of Allâh's Messenger (ﷺ) on the built edge of the well and hung his legs in the well as the Prophet (ﷺ) did and uncovered his legs. I then returned and sat (at the gate). I had left my brother performing ablution and he intended to follow me. So I said (to myself). If Allâh wants good for so-and-so (i.e. my brother) He will bring him here." Suddenly somebody moved the door. I asked, "Who is it?" " He said, 'Umar bin Al-Khattab. I asked him to wait, went to Allâh's Messenger (ﷺ) greeted him and said, 'Umar bin Al-Khattab asks the permission to enter." He said, "Admit him, and give him the glad tidings that he will be in Paradise." I went to 'Umar and said, "Come in, and Allâh's Messenger (ﷺ) gives you the glad tidings that you will be in Paradise." So he entered and sat beside Allâh's Messenger (ﷺ) on the built edge of the well on the left side and hung his legs in the well. I returned and sat (at the gate) and said, (to myself), "If Allâh wants good for so-and-so, He will bring him here." Somebody came and moved the door. I asked " Who is it?" He replied, "Uthman bin ' Affân." I asked him to wait and went to the Prophet (ﷺ) and informed him. He said, "Admit him, and give him the glad tidings of entering Paradise after a calamity that will befall him." So I went up to him and said to him, Come in; Allâh's Messenger (ﷺ) gives you the glad tidings of entering Paradise after a calamity that will befall you." Uthmân then came in and found that the built edge of the well was occupied, so he sat opposite to the Prophet (ﷺ) on the other side. [5:23-0.B]
