Is asking questions about Islam kufr?

I’m just wondering about this ruling on asking questions about Islam. Some say it’s discouraged and some say it’s haram but my question is would it be considered kufr if you ask too many questions about Islam. So in my case I asked “it doesn’t make sense, why does Prophet Muhammad love us more than our mother loves us if he didn’t meet us in the first place?” Edit: is my question in quotations considered doubt
