Saeed bin Musayyib says that Abu Musa Ash'ari (may Allah be pleased with him) informed me that he performed ablution in his house, then went out. Abu Musa says: I said, "Today I will not leave the company of the Messenger of Allah (peace and blessings be upon him) all day; I will stay with him." He says: Then I came to the mosque and inquired about the Prophet (peace and blessings be upon him). The people said that he had gone out in that direction. So I followed in the footsteps of the Prophet (peace and blessings be upon him) and kept asking people about him. While walking, I found out that the Prophet (peace and blessings be upon him) had gone into a garden at the place of Aris. I sat near the door, which was made of palm branches, until the Messenger of Allah (peace and blessings be upon him) finished relieving himself and had performed ablution, then I walked towards him. I saw that the Prophet (peace and blessings be upon him) was sitting on the edge of the well of Aris, with both his shins uncovered and dangling in the well. So I greeted the Prophet (peace and blessings be upon him) and then returned to sit near the door. I said (to myself): Today I will be the doorkeeper/guard of the Prophet (peace and blessings be upon him). Meanwhile, Abu Bakr (may Allah be pleased with him) came and pushed the door. I asked, "Who is it?" He said, "Abu Bakr." I said, "Wait a moment." Then I went and said, "O Messenger of Allah! Abu Bakr seeks permission to enter." The Prophet (peace and blessings be upon him) said, "Let him in and give him glad tidings of Paradise." I came and told Abu Bakr, "Enter, and the Messenger of Allah (peace and blessings be upon him) has given you glad tidings of Paradise." So Abu Bakr entered and sat on the right side of the Prophet (peace and blessings be upon him) on the same edge, with both his legs dangling and his shins uncovered, just as the Prophet (peace and blessings be upon him) was sitting. I returned and sat down again, and I had left my brother (Amir) performing ablution at home. I said, "If Allah wills good for so-and-so (i.e., my brother), He will bring him here." Meanwhile (what do I see but) someone started shaking the door. I asked, "Who is it?" The reply came, "Umar bin Khattab." I said, "Wait." Then I went to the Messenger of Allah (peace and blessings be upon him), greeted him, and said, "Umar bin Khattab seeks permission to enter." He said, "Let him in and give him glad tidings of Paradise." So I went and said, "Enter, and the Messenger of Allah (peace and blessings be upon him) has given you glad tidings of Paradise." So he also entered and sat on the left side of the Prophet (peace and blessings be upon him) on the same edge, and both his legs were dangling in the well. Then I returned and sat (at the door). I said, "If Allah wills good for so-and-so (Amir), He will bring him here." Meanwhile, another man shook the door. I said, "Who is it?" He replied, "Uthman bin Affan." I said, "Wait." Then I went to the Messenger of Allah (peace and blessings be upon him) and informed him, so he said, "Let him in and give him glad tidings of Paradise, but he will be afflicted with a calamity." I came and said to him, "Enter, and the Messenger of Allah (peace and blessings be upon him) has given you glad tidings of Paradise, but with a trial that will befall you." So he also entered and saw that a part of the edge was filled, so he sat on the other side, facing the Prophet (peace and blessings be upon him). Shareek said that Saeed bin Musayyib said: I derived from this hadith that their graves would also be in this order. (And so it happened that Uthman (may Allah be pleased with him) did not find a place in that chamber, so he was buried in Baqi' in front of the Prophet (peace and blessings be upon him)).
