"O Allah, do not make my grave an idol that is worshiped. Allah cursed the people who took the graves of their prophets as places of worship."

"The places that are dearest to Allah are the mosques, and the places that are most hateful to Allah are the marketplaces."

While we were in the mosque with the Messenger of Allah (may Allah's peace and blessings be upon him), a Bedouin came and began to urinate in the mosque. The Companions of the Messenger of Allah (may Allah's peace and blessings be upon him) said: Stop! Stop! He said: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Do not interrupt him; let him." So they left him until he finished urinating. Then the Messenger of Allah (may Allah's peace and blessings be upon him) called him and said to him: "These mosques are not appropriate for anything of this kind of urine or filth. They are only for the remembrance of Allah Almighty, prayer, and recitation of the Qur’an" or as the Messenger of Allah (may Allah's peace and blessings be upon him) said. He said: Then he ordered a man from among the people who brought a bucket of water and poured it over the affected area.

"When any of you enters the mosque, let him say: 'Allahumma iftah li abwāba rahmatik' (O Allah, open for me the gates of Your mercy). And when he leaves, let him say: 'Allahumma inni as’aluka min fadlik' (O Allah, I ask You of Your bounty)."

"Do not prevent the female servants of Allah from (going to) the mosques of Allah, but let them go out without perfume and unadorned."

'Uthmān ibn' Affān (may Allah be pleased with him) wanted to build the mosque, but the people did not like this idea, and they wished that he should keep it as it was. Thereupon, he said: "I heard the Messenger of Allah (may Allah's peace and blessings be upon him) say: 'He who builds a mosque for Allah, Allah will build for him the like of it in Paradise.'"
