The Mosque is the central place of worship for all Muslims and there are rules guiding behaviour and usage of the Masjid. These etiquette are taught to us by Allah and His Messenger and should be practiced with diligence in hope of coming closer to Allah and being among those whose hearts are attached His Houses.
1. Adopt a spirit of reverence and honour for the Mosque. “And whoever honors the symbols of Allah – indeed, it is from the piety of hearts.” [Al-Hajj Q22:32]
2. Be on your best behaviour:
When invited into a home, you are expected to be of excellent behaviour, how much more of being a guest in the House of Allah (S.W.T).
3. Leaving your house in a state of purity:
It was narrated that the Messenger of Allah said, “He who purifies himself in his house and then walks to one of the houses of Allah for performing an obligatory prayer, one step of his will wipe out his sins and another step will elevate his rank (in Paradise).” (Muslim)
4. Modest Mode of dressing is key: Allah (s.w.t) says, “O Children of Adam! Wear your beautiful apparel at every time and place of prayer.” [Al-Araf Q7:31]
5. Reading the Prophetic supplication for leaving to the Masjid. In this supplication, the believer asks Allah to increase him in this spiritual light and to surround him with light from all directions.
6. Park properly:
The least branch of Iman is the removal of harmful object from the road. Today, some people park their cars wherever they want for long periods of time and block the path to the masjid's entrance, constricting the road and bringing about difficultly for the people when they leave the Friday prayer.
7) Reading the supplication for entering the masjid, and entering with your right foot.
8) Making Salam to the Masjid: The Prophet (Saw) said, “When one of you comes to the mosque, he should pray two rak'at before he sits.”
9) Lowering voices and refraining from disturbing those who are praying. Abu Sa'eed al-Khurdi (may Allah be pleased with him) reports that the Prophet was making seclusion (i'tikaf) in the mosque and he heard the people reciting aloud. He removed the covering and said: “Verily, each of you is in a private conversation with his Lord so you should not disturb each other. And you are not to raise your voices against each other in the recitation.” (Abu Dawud)
10) Keep the MAsjid clean at all times: The Masjid is a place of worship and should be kept clean at all times. 'Aishah reports that the Prophet ordered that mosques be built in residential areas and that they be cleaned and perfumed. (ibn Hibban)
