Brief explanation:

The mosque is a good place and also where the people are good, therefore he should be purified from foul odors and vice versa continues diwangikan with fragrant odors. It is far more mainstream and more important than decorating-decorate and elevate the mosque, because the two deeds is not the guidance of the Prophet-alaihishshalatu yours respectfully.

So this hadeeth shows the ban firmly entered the mosque to anyone who brings bad smell, both in body and in her mouth. Why because the angels will feel disturbed as human beings therefore also disturbed by it. Therefore he who smells his body, then he should shower first or at least wear perfumes that can eliminate the smells his body before he went to the mosque. Similarly, people who mouth odor by eating a raw onion-bawangan (not cooked / fried) or been drinking alcohol or smoking cigarettes out and the like that cause malodorous mouth, then he should first remove the smell of her mouth before going to the mosque. If not then he has fallen into the prohibition of the Prophet-alaihishshalatu yours respectfully-that is the hadeeth of Ibn 'Umar, and Jabir above.

Conversely Islam mosque menuntunkan for always cleared of all the things that can disturb kekhusyuan worship and perfume the mosque with air freshener or by burning bukhur (fragrant wood smoke.)

Maintain peace of people who worship which is the core of the construction of mosques, including beyond the limit and therefore mubazzir when the mosque was built or renovated decorated or not for this purpose. Truly yours respectfully alaihishshalatu-Prophet has said raise terlarangnya mosque because it is an act of infidels. What is meant by elevating the mosque here is not to build in 2 floors or more, because it is sometimes necessary to accommodate the pilgrims. But that meant in this prohibition is to raise the roof of the mosque without a purpose, as the high roofs of the church. Also included in this prohibition is to decorate mosques, garnished with proceedings that are not beneficial and even tended to interfere with people who pray, for example by writing calligraphy on the wall or a patterned tiles laid in front of or below (on mat) the person who prays, who can unsettle person who prays. And so on.

Among the law relating to the mosque is, should the Muslims build a mosque for each settlement. Which aims to turn the settlement over the syiar Islam and to facilitate the Muslims in worship to Allaah. And they should not build two or more mosques within a settlement except with the permission of the government and has reason syar'i in its development. Because it Allaah and His Messenger, denounced the construction of mosques which aims only to emulate the other mosques, and also because it will cause divisions among the Muslims and mempersedikit number of pilgrims at the first mosque.
