Islam itself is not worshipped, God Allah is. There are mosques/masjeds that are built for congregation in the 5 daily prayers for both men and women. Prayers can also be done in the house, outside, any where for that matter, and that is one major form of worship. Other worship forms can be as little as giving a smile as Islam teaches that a smile is a blessing and rewards are given to the believer that smiles to another...

It depends entirely on how the question is read. If the question is asking what is the largest religion that is still growing, the answer would be Christianity since there are more and more Christians born and converted every day than convert out or die. If the question is asking what religion is growing by the largest numbers of new followers (both births and converts), then the answer would be Islam, since the population growth in Muslim-majority countries has made Islam the religion with the most new adherents daily. If the question is asking what religion has the greatest percentage of growth, then this would be a contest between a number of very small religions which have high percentage increases, but low current population counts, such as Baha'i or Jehovah's Witnesses. Although these cannot match the numerical growth of Christianity or Islam, the thousands of converts and newborns have a much higher relative to the <20 million adherents to the religion.
They do not. They go to mosques to worship. A mosque is a place of collective worship for Islamic people, in a way similar to a church for Christians, a synagogue for Jewish people, a gurudwara for Sikhs, a temple for Hindus or Buddhists, and so on.
Islam is a religion not a spiritual leader. Islam is not dead.

Islam is the religion and Muslims are the followers of the Islam religion.
