In the name of Allah, most Gracious, most Merciful.

We’ve all experienced this at the mosque at some point. You get to the mosque late and you can’t find a spot to pray so you find a gap between two brothers and force your way in; or you get there early to get a good seat and some late-comer squeezes between you and the brother beside you and suddenly you’re curled up to one side thinking… why me?
The next time you face this dilemma, think about the following Hadith:
The Prophet (p.b.u.h) said, “Whoever takes a bath on Friday, purifies himself as much as he can, then uses his (hair) oil or perfumes himself with the scent of his house, then proceeds (for the Jummah prayer) and does not separate two persons sitting together (in the mosque), then prays as much as (Allah has) written for him and then remains silent while the Imam is delivering the Khutbah, his sins in-between the present and the last Friday would be forgiven.”
The Hadith emphasizes the importance of etiquette at the Mosque. Be courteous towards your fellow worshippers, this will benefit you and those around you and will facilitate a healthy, peaceful praying environment. Most Mosques and Prayer halls struggle to cope with the crowd at Jummah Prayers so you are bound to have a space issue and will sometimes be forced to inconvenience fellow worshippers, be polite about it and there will be reward in that too Insha Allah. If you do a righteous act, do it for Allah and likewise, if you restrain yourself from committing a sin, do it for Allah.
Jummah Mubarak!
…and remember… “The deeds most loved by Allah are those done regularly, even if they are small.”
