Following this logic saving a friend or a partner will protect you in the future. It is a natural behaviour that many animals would never survive without. If elephants did not help each other defend against predators they would be extinct by now because 1 on 1 (especially children and females) they are not fit to fight off fast, carnivorous predators.
If you actually read the link I included, you will see that the chimps involved helped unrelated humans and conspecifics. If this is simply based on instinct and is a natural behavior, I propose the same is true with humans. After all, chimps are closely related to us which makes looking at their behaviors particularly relevant. I believe religions (not just Abrahamic religion) likely reinforce some of these behaviors in humans, but I believe that altruistic behavior came first, NOT religion. Religion also carries a lot of other not-so-good baggage with it; it pits US against THEM. I believe that is also part of the reason for the existence of religion in the first place; it creates a type of tribal unity.
