Why do we underestimate Allah’s ability? A thought on Al-Qadeer, sabr, and the "illusion" of holding onto du'a

Assalamu Alaikum everyone, I've been thinking a lot about how we see Allah's power, especially through His names Al-Qadir and Al-Qadeer-the One who is fully capable over all things. We often hear the common advice when a du'a isn't answered quickly: "If Allah didn't give it to you, it's because He knows it's not good for you." While it's true that Allah knows what's best, I feel like we sometimes use this to unintentionally put limits on His power. Allah is Al-Qadeer. He doesn't just work around what already exists; He creates reality itself. If something we really want isn't "good" for us at the moment, Al-Qadeer can change that thing, fill it with khair, and make it completely good for us. He can flip your whole story in an instant. I'm talking from my own journey. For the past two years, I've been making du'a non-stop for a specific matter. I haven't just been asking for the thing-I've been begging Allah to place khair in it for me, and then bless me with it. I've taken this du'a to the most sacred places a believer can go. I've cried over it in the depths of Tahajjud, stood weeping on the Day of Arafat, begged during Umrah, and poured my heart out in the Rawdah of the Prophet (peace be upon him). Through all this, I'm practicing sabr and firmly trusting that Allah will give it to me at the perfect time. But when you pray for the same thing for years, people start talking. They see your persistence and call it an "unhealthy obsession." They see your steady hope and label it a "delusion." But why should I listen to people when I know who I'm asking? Omar Ibn Al-Khattab (may Allah be pleased with him) famously said, "Nothing changes Qadr except du'a." If fate itself can be changed by du'a with Allah's will, why do we ask Him with small requests or lose hope because of time? Why do you think we, as an Ummah, sometimes slip into a passive attitude instead of begging Al-Qadeer to transform our situations? Has anyone else held onto a du'a for years despite everything and seen Al-Qadeer rewrite your story? I'd love to hear your reflections and experiences.
