Ibn Uyaynah says that I asked Amr bin Dinar, "Have you heard Jabir bin Abdullah (may Allah be pleased with him) narrate this hadith, that the Prophet Muhammad (peace be upon him) said to a man who was passing through the mosque with arrows, 'Hold them by their tips'?" Amr bin Dinar said, "Yes, I have heard this hadith from Jabir (may Allah be pleased with him)." This hadith is from Makhzumi.

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates from the Messenger of Allah (peace and blessings be upon him) that the Noble Prophet (peace and blessings be upon him) instructed a man, who was distributing arrows in the mosque, to hold the arrowheads while passing through the mosque.

Sayyiduna Abu Musa (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When any one of you passes through our mosque or our market carrying arrows, he should hold them by their heads, so that they do not harm any Muslim." Or he said: "He should hold their heads."

And in this is evidence that the right to the mosque belongs to the one who comes to it first. No person has more right over any part of the mosque than another. Allah Almighty says: «‏‏‏‏وَأَنَّ الْمَسَاجِدَ لِلَّهِ» ‏‏‏‏ [ سورة الجن: 18 ] "Indeed, the mosques are for Allah."

Sayyiduna Abdur Rahman bin Shibl (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) forbade pecking like a crow (in prayer), spreading the arms like a beast, and reserving a specific place or spot in the mosque for oneself in the manner that a camel designates a place for sitting.

Sayyiduna Abu Qatadah (may Allah be pleased with him) narrates that the Messenger of Allah (peace be upon him) came to a group of the Ansar while they were building a mosque. So the Prophet (peace be upon him) instructed them: "Make it spacious, you will fill it (with your numbers)."

Hazrat Abu Qilabah Jarami narrates that we were going towards the place of Zawiyah with Sayyiduna Anas (may Allah be pleased with him) when we passed by a mosque while the time for the morning prayer had already come. So Sayyiduna Anas (may Allah be pleased with him) said, "If we pray in this mosque (it would be better), because some people pray in another mosque." They asked, "Which mosque?" So we mentioned a mosque. Sayyiduna Anas (may Allah be pleased with him) said, "Indeed, the Messenger of Allah (peace and blessings be upon him) said: 'A time will come upon the people when they will take pride in their mosques. They will not populate them except a little.' Or he said: 'They will populate them very little.'" Imam Abu Bakr (may Allah have mercy on him) says that "Zawiyah" is a place two farsakhs from Basrah (where Sayyiduna Anas (may Allah be pleased with him) had land and a house).

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Among the signs of the Hour is that people will boast and take pride regarding the mosques."

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The Hour will not be established until people begin to boast and take pride in (the construction and adornment of) mosques."

Sayyiduna Abdullah (may Allah be pleased with him) narrates that the Prophet’s Mosque during the blessed era of the Messenger of Allah (peace and blessings be upon him) was built of bricks, its roof was made of palm branches, and its pillars were of palm wood. Sayyiduna Abu Bakr (may Allah be pleased with him) did not add anything to it (during his era). Sayyiduna Umar (may Allah be pleased with him) expanded it (making it spacious and wide). He rebuilt it on the foundations from the blessed era of the Messenger of Allah (peace and blessings be upon him) with bricks and palm branches, and had its pillars made of wood again. Then Sayyiduna Uthman (may Allah be pleased with him) made changes to it and expanded it considerably. He had its walls built with decorated stones and lime, and its pillars constructed from decorated stones, and its roof made from fine teak wood. In the narration of Muhammad bin Yahya, the words are as follows:“And its pillars were made of palm wood. And he did not mention lime.”
