Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him):
A black man or a black woman used to sweep the mosque. When he (or she) died, the Prophet (peace and blessings of Allah be upon him) asked about him (or her). The people said, "He (or she) has died." He said, "Why did you not inform me? (Well then) show me his (or her) grave." So the people showed it to him, and he (peace and blessings of Allah be upon him) offered the funeral prayer for him (or her).

Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) says that when the verses of Surah Al-Baqarah regarding usury were revealed, the Prophet Muhammad (peace be upon him) went towards the mosque and recited these verses before the people. Then the Prophet (peace be upon him) prohibited the trade of alcohol.

Narrated Abu Huraira (may Allah be pleased with him) from the Prophet (peace and blessings of Allah be upon him) that he said: "A rebellious jinn came before me last night (or he said a similar word) to interrupt my prayer, but Allah gave me control over him. I intended to tie him to one of the pillars of the mosque so that you all could see him in the morning. Then I remembered the supplication of my brother Solomon (peace be upon him): 'My Lord, grant me a kingdom such as will not belong to anyone after me.' (Surah Sad 35) (So the Prophet, peace be upon him, humiliated him and let him go.)"

Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) says that on the day of (the Battle of) Khandaq, Sayyiduna Sa'd (may Allah be pleased with him) was wounded in the median vein (a name of a vein), so the Noble Prophet (peace and blessings be upon him) set up a tent in the mosque so that he could visit him closely. Then suddenly, while there was also a tent of Banu Ghifar in the mosque, blood started flowing towards them, so those people said, "O people of the tent! What is this that is coming to us from your side?" (When they looked,) they saw that blood was flowing from the wound of Sayyiduna Sa'd (may Allah be pleased with him), and thus he was martyred from this wound.

Umm Salamah (may Allah be pleased with her) said: I complained to the Messenger of Allah (peace and blessings of Allah be upon him) that I was ill, so he said: "Perform Tawaf riding behind the people." So I performed Tawaf, and the Messenger of Allah (peace and blessings of Allah be upon him) was praying in a corner of the Ka'bah. He was reciting Surah At-Tur.

Narrated from Sayyiduna Anas (may Allah be pleased with him) that two persons from among the companions of the Prophet (peace and blessings of Allah be upon him) left from the presence of the Prophet (peace and blessings of Allah be upon him) on a dark night. (One of them was Sayyiduna ‘Abbad bin Bishr, may Allah be pleased with him, and I think the other was Sayyiduna Usayd bin Hudayr, may Allah be pleased with him.) And with both of them were two lamps (of light) which were shining in front of them. Then when they separated, one (lamp) remained with each of them, until they reached their homes.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) delivered a sermon one day and said: "Indeed, Allah, the Exalted, gave a servant the choice between (the world) and that which is with Allah, so he chose that which is with Allah." Upon hearing this, the leader of the believers, Abu Bakr as-Siddiq (may Allah be pleased with him), began to weep. I said to myself, "What is making this old man cry? If Allah gave a servant the choice between the world and that which is with Allah, and he chose that which is with Allah, then what is there to cry about?" But in the end, it became clear that the servant referred to was the Messenger of Allah (peace and blessings be upon him) himself, and Abu Bakr as-Siddiq (may Allah be pleased with him) was the most knowledgeable among us. Then the Prophet (peace and blessings be upon him) said: "O Abu Bakr! Do not weep. Indeed, the person who has done the greatest favor to me, with his companionship and his wealth, is Abu Bakr as-Siddiq. And if I were to take a close friend (khalil) from my ummah, I would certainly take Abu Bakr, but the brotherhood of Islam and its love is sufficient. And in the mosque, all the doors except the door of Abu Bakr should be closed."

Narrated Ibn Abbas (may Allah be pleased with them) that the Messenger of Allah (peace and blessings of Allah be upon him), during his illness in which he passed away, came out with his head tied with a bandage and sat on the pulpit. Then he praised and glorified Allah, then said: "O people! There is no one who has done more favor to me with his life and wealth than Abu Bakr, and if I were to take anyone from among the people as a close friend (khalil), I would certainly have taken Abu Bakr as a close friend, but the brotherhood of Islam is superior. Close every window in this mosque except the window of Abu Bakr."

Narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that when the Noble Prophet (peace and blessings of Allah be upon him) came to Makkah, he called for Uthman bin Talha (may Allah be pleased with him). He opened the (Ka'bah's) door, then the Noble Prophet (peace and blessings of Allah be upon him), Bilal, Usama bin Zaid, and Uthman bin Talha (may Allah be pleased with them all) went inside. After that, the door was closed. Then the Prophet (peace and blessings of Allah be upon him) stayed there for a little while, after which everyone came out. Ibn Umar (may Allah be pleased with them both) says that I hurried towards the Ka'bah and asked Bilal (may Allah be pleased with him), so he informed me that the Noble Prophet (peace and blessings of Allah be upon him) had prayed inside the Ka'bah. I asked, "At which place?" He said, "Between the two pillars." Ibn Umar (may Allah be pleased with them both) says, "I missed asking him how much prayer the Prophet (peace and blessings of Allah be upon him) had performed."

Narrated Abdullah bin Umar (may Allah be pleased with them): A man asked the Prophet (peace be upon him) while he was on the pulpit about the prayer at night. The Prophet (peace be upon him) said: "Pray two by two (rak'ahs)." Then when any one of you fears that morning is approaching, let him pray one rak'ah, and that one rak'ah will make what he has prayed odd (witr) for him. And Ibn Umar (may Allah be pleased with them) used to say: "Make your last prayer at night witr, because the Prophet (peace be upon him) ordered this."
