Community is such an important part of life... we humans are social creatures.
Community is a huge factor in converting to Islam.
A positive experience can make people feel at home in the deen. A negative one can crush the new tiny bud of belief.
Many people don't realize just how important support is in the beginning. Some people will say "if you really believe, you can just do it on your own." While it is true that Allah is the best helper, I believe that He uses other people to help. For someone who is new and isolated and maybe broken from their family and very confused, having no support can be the straw that broke the camel's back.
Left alone, the shaytan can amplify and twist every single tiny thought.
The shaytan likes to divide and conquer. That is why Muslims are supposed to stick together in our family called ummah. That is why when new faces show up at the masjid, or the forum, or the blog it is so so so important that we take them under our wing and build a community experience for them and for ourselves.
'You will see the believers in their mutual kindness, love and sympathy just like one body. When a limb complains, the whole body responds to it with wakefulness and fever' (Muslim and Bukhari)
Prophet Muhammed salAllahu 3alaihi wa sallam said
"You shall not enter Paradise until you believe; and you will not bellieve until you love one another. Shall I not guide you to a thing? Which when done , will make you love one another: Spread the greeting of Salam among you"- (Muslim)
The Messenger of Allah (salAllahu 3alaikhi wa sallam) said : A muslim is a brother to a Muslim: Neither he wrongs him, nor hands him over (to another). And whoso comes in need of his brother , Allah comes in his need ;and whoso removes a calamity of a Muslim, Allah will remove a calamity from the calamities of the Resurrection Day, and whoso conceals the faults of a Muslim, Allah will conceal his sins on the Resurrection Day' (Bukhari and Muslim)
