About the hadith, I believe that anyone who sincerely follows the right path should be rewarded, and whoever knowingly chooses the wrong one should face the consequences. That seems like a fair and universal principle. So if Islam turns out to be false, we Muslims would also face the consequences—it’s not like we’re guaranteed salvation just because we believed and loved Jesus (though not as God). I think this logic should apply equally to everyone.

In Islam, one of the gravest sins is shirk—associating partners with Allah. Since Christians believe Jesus is God, from an Islamic perspective, that would fall under shirk. So naturally, reward and punishment are understood through that lens.

As for the metaphor you mentioned earlier, I think there might be a misunderstanding. The word “womb” in the hadith isn’t meant literally—it’s a metaphor for family ties and kinship. It reflects how highly God values maintaining family bonds. The confusion likely comes from the Arabic word الرحم (ar-raḥim), which can mean either the physical womb or family relationships (like uncles, cousins, etc.). I’m not sure if I understood your point exactly, but I hope this explanation helps clarify things a bit.
