What is the ruling on the unification of Adhan?
All perfect praise be to AllahThe Lord of The Worlds, and may His peace and blessings be upon our Prophet Muhammad and upon all of his family and companions. The unified Adhan is an act of Sunnah performed on behalf of a city's population. In addition, any Masjid that doesn’t have a Mua'than (The person who calls for prayers) and doesn`t raise the Adhan misses the reward of this great act. This is because Adhan should be raised for every group of people. However, the unified Adhan should be called in one Masjid and heard through all other Masjids. And Allah Knows Best.

In Islam, it isn`t permissible for a woman to wear garment revealing her beautiful shape and arousing men`s sexual desire. This is whether the garment is transparent or skin-tight showing the size of her private parts. A Muslim woman`s garment must be loose and not revealing since she will be accountable for this before Allah The Almighty on the Day of Judgement. And Allah The Almighty Knows Best.
