Narrated from Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) came to the house of Sayyidah Fatimah al-Zahra (may Allah be pleased with her) and did not find Sayyiduna Ali (may Allah be pleased with him) at home, so he (peace be upon him) said:“Where is your cousin?”She replied that something (a dispute) had happened between me and him, so he became angry with me and left, and did not sleep here. So the Messenger of Allah (peace and blessings of Allah be upon him) said to a person:“See where he is.”He (the person) went and came back and said that he is sleeping in the mosque. So the Messenger of Allah (peace and blessings of Allah be upon him) went (to the mosque) and he (Ali) was lying down, his cloak had fallen off his side and there was dust on his (body), so the Messenger of Allah (peace and blessings of Allah be upon him) began to brush the dust off him and was saying:“O Abu Turab! Get up. O Abu Turab! Get up.”

Narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that during the time of the Messenger of Allah (peace and blessings of Allah be upon him), the mosque was built of unbaked bricks, its roof was made of palm branches, and its pillars were of palm wood. Then, Amir al-Mu'minin Sayyiduna Abu Bakr (may Allah be pleased with him) did not make any addition to it, and Amir al-Mu'minin Sayyiduna Umar (may Allah be pleased with him) made an addition to it and rebuilt it with unbaked bricks and palm branches, in accordance with the building during the time of the Messenger of Allah (peace and blessings of Allah be upon him), and again set up wooden pillars.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) began to narrate a hadith (one day) until he reached the account of the construction of the mosque (the Prophet's Mosque).

When the Prophet Muhammad (peace and blessings be upon him) saw him, he began to dust the dirt off his (body) and kept saying: "Woe to Ammar's distress! A rebellious group will kill him; they will call him towards Paradise, and he will call them towards Hellfire." Abu Sa'id (may Allah be pleased with him) says that Ammar used to say: "I seek refuge with Allah from tribulations."

Narrated from Sayyiduna Uthman bin Affan (may Allah be pleased with him) that when people were talking about him, at the time when he (Uthman) built the mosque of the Messenger of Allah (peace and blessings of Allah be upon him), he said: "You have said much (about me), although I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: 'Whoever builds a mosque, seeking the pleasure of Allah, Allah will build for him a house in Paradise like it.'"

Respond on behalf of the Messenger of Allah (peace and blessings of Allah be upon him) (to the polytheists), O Allah! Support Hassan with the Holy Spirit.’”So Sayyiduna Abu Hurairah (may Allah be pleased with him) said:“Yes (I heard it).”

Narrated from Sayyiduna Ka'b bin Malik (may Allah be pleased with him) that he demanded repayment of a debt from Ibn Abi Hadrad in the mosque.

The Prophet (peace and blessings be upon him) came to them, lifted the curtain of his chamber, and called out: "O Ka'b!" He replied, "At your service, O Messenger of Allah!" The Prophet (peace and blessings be upon him) said: "Reduce some of your debt," and he gestured, meaning half (reduce it by half). Ka'b (may Allah be pleased with him) said, "O Messenger of Allah! I have reduced it." The Prophet (peace and blessings be upon him) then said (to Ibn Abi Hadrad): "Get up and pay it."
