I think Islam is like water. Everyone in the world needs it. There are sources of it all around the earth. It's a little different everywhere you go. It's natural.
Some people have polluted their water supply to the point that it causes them harm, but they drink it anyway. Some people have no water at all. These people I want to help. I will do what I can to provide them with clean water to drink.
Some people are so obsessed with making water "pure" that they distill it to the point that all of the natural minerals are gone and it has no flavor. They insist that this how water is supposed to be, but in reality, water is never naturally like this.
Others want to import their water from overseas. They insist that this water is the best water and they force it on their children, when in reality that water is no better than others. In fact, the local water may even be cleaner.
Some think it doesn't matter what we drink, that we should just relax and drink from the tap like everybody else, when in reality that water has chemicals that we should be smart enough to avoid.
My advice? Don't be too strict or too loose, but take moderate approach. Don't limit yourself to only a certain kind of water, but be open to new sources, and don't obsess over its purity, but definitely put it through a filter. Most of all, remember that water is a blessing from the Divine, so be thankful that you have it and share it with those who need it.
