According to Christianity, is only the Christian faith a gift from God?

At least in the Catholic Church (with which I am most familiar), it is stated that Faith is a gift from God. Point 179 in the [Catechism](http://www.vatican.va/archive/ENG0015/__P12.HTM) reads: > 179. Faith is a supernatural gift from God. In order to believe, man needs the interior helps of the Holy Spirit. A [related question](https://christianity.stackexchange.com/questions/15042/is-faith-in-the-holy-trinity-a-choice-or-a-gift) has an accepted answer on the same lines. Now, we know that people from other (even extinct) religions also have faith in their particular god(s). Within those religions, some have more faith than others, and there is also a group which have lost their faith, perhaps because of conversion to a different faith. According to Christianity, is their faith also a gift from God? Why would God give to some a partial/incorrect gift and a complete/correct gift to others? What is the Catholic (and other Christian) teaching on this respect? P.S. This question emerged in the context of a conversation with a Muslim friend. Some of them also believe that faith is a blessing from God (e.g. [here](https://aboutislam.net/family-society/culture/faith-choice-gift/)) . Hence the question of the many but different gifts.
