1. Dress appropriately when coming to the musjid.
یٰبَنِیۡۤ اٰدَمَ خُذُوۡا زِیۡنَتَکُمۡ عِنۡدَ کُلِّ مَسۡجِدٍ
Allah Ta’ala says, “O children of Aadam (alayhis salaam), take your adornment at the time of performing salaah in the musjid.”
2. Remove any foul odour from your body, clothing or mouth before entering the musjid e.g. after eating onions or something with a foul odour, standing near a fire, etc.
عن جابر رضي الله عنه قال قال رسول الله صلى الله عليه وسلم من أكل من هذه الشجرة المنتنة فلا يقربن مسجدنا فإن الملائكة تتأذى مما يتأذى منه الإنس (صحيح مسلم، الرقم: 564)
Hazrat Jaabir (radhiyallahu anhu) reports that Hazrat Rasulullah (sallallahu alaihi wasallam) said, “The one who eats from this foul-smelling tree (garlic or onions) should not come close to our musjid, for the malaa’ikah (angels) are inconvenienced through the bad odour of those things through which humans are inconvenienced.”
3. Apply itr before coming to the musjid if you are able to.
عن أبي سعيد الخدري رضي الله عنه أن رسول الله صلى الله عليه وسلم قال غسل يوم الجمعة على كل محتلم وسواك ويمس من الطيب ما قدر عليه (صحيح مسلم، الرقم: 847)
Hazrat Abu Sa’eed Khudri (radhiyallahu anhu) reports that Hazrat Rasulullah (sallallahu alaihi wasallam) said, “Every baaligh person should perform ghusl on the Day of Jumuah, make miswaak and apply any itr that he is able to.”
4. Proceed to the musjid calmly and in a dignified manner. Do not come to the musjid running.
عن أبي هريرة رضي الله عنه قال سمعت رسول الله صلى الله عليه وسلم يقول إذا أقيمت الصلاة فلا تأتوها تسعون وأتوها تمشون عليكم السكينة فما أدركتم فصلوا وما فاتكم فأتموا (صحيح البخاري، الرقم: 908)
Hazrat Abu Hurairah (radhiyallahu anhu) once mentioned, “I heard Rasulullah (sallallahu alaihi wasallam) say, ‘When the iqaamah is called out for salaah, then do not proceed towards the salaah whilst you are running. Rather, come walking with calmness and tranquillity. Whatever portion of the salaah you obtain with the imaam, then perform it; and whatever portion you missed, then complete it (after the imaam completes the salaah).’”
5. It is better for one to be in the state of wudhu when entering the musjid.
عن أبي هريرة رضي الله عنه أن رسول الله صلى الله عليه وسلم قال لا يزال العبد في صلاة ما كان في مصلاه ينتظر الصلاة وتقول الملائكة اللهم اغفر له اللهم ارحمه حتى ينصرف أو يحدث قلت ما يحدث قال يفسو أو يضرط (صحيح مسلم، الرقم: 649)
Hazrat Abu Hurairah (radhiyallahu anhu) reports that Hazrat Rasulullah (sallallahu alaihi wasallam) said, “As long as one remains on his musalla awaiting salaah, he receives the reward of one who is in salaah. The malaa’ikah (angels) continue to make dua for him saying, ‘O Allah Ta’ala, forgive him! O Allah Ta’ala, have mercy on him!’ He continues receiving reward until he leaves the musjid or hadath occurs while he is in the musjid.” A Sahaabi (radhiyallahu anhu) asked, “How does hadath occur?” Hazrat Rasulullah (sallallahu alaihi wasallam) replied, “Through passing wind (breaking his wudhu).”
