The actions of the believer while visiting the Houses of Allah must vary from his normal actions outside of the masjid. This is due to his awareness of the sacredness of this house. He keeps in mind at all times, that he is visiting a place that has been established for the worship of Allah, and therefore, that which takes place in it should be mainly focused on actions which draw one nearer to Allah.
Subsequently, the following actions are forbidden:
1. Speaking loudly or about matters of no real importance
Al Saeeb bin Yazeed mentioned: I was standing in the masjid one day when I felt someone pocking me. When I turned around I saw that it was ‘Umar bin al Khattab. He instructed me to bring him two men who were in the masjid raising their voices. When I brought him the two men ‘Umar asked them: Where are you from? They replied: We are from Taif. ‘Umar said: If you were from this city, I would have beaten you! You were raising your voices in the masjid of the Prophet?!
(Sahih Bukhari)
Sa’eed bin al Musayib mentioned:
“When a person sits in a masjid, indeed he is sitting for the worship of his Lord, and therefore he should only speak with that which is good.” (Tafsir al Qurtubi)
It is also befitting to remind those whom bring children to the Houses of Allah that they are responsible for monitoring their children and making sure their behaviour is not a disturbance to fellow worshippers. The Prophet of Allah (may the peace and blessings of Allah be upon him) said:
“All of you are guardians, and everyone will be questioned concerning those under his care.”(Sahih Bukhari and Sahih Muslim)
Although this hadith is general, without a doubt, it applies to those whom accompany their children along with them to the Houses of Allah. The guardian should teach those in his care the correct manners of visiting the house of worship. He should not allow his child to run around and disturb others who are seeking nearness
