I am still waiting to learn one single fact about Islam that doesn't show it to be utterly reprehensible. I am willing to keep an open mind - but it is getting harder to do so.
Islam does have a few redeeming qualities, though the negative far outweigh the positives. But, since you asked, the positives are
1. Emphasis on one God
2. Against idolatory
3. Emphasis on charity
4. Emphasis on equality of all humans.
I won't go into the negatives. I wrote a book on that.
