A doubt regarding the phrase in the prayer of istikhara (O Allah, if You know)

Question:
Thank you, Abu. The second point is in the hadith: Make it easy for me. And if there is no good for me in it, turn it away from me. My question is about the phrase "if You know." Allah, Glorified and Exalted is He, knows what was and what will be. I am inquiring about this matter. And regarding zakah, as I said, thank you. To the question of the brother Abu Khalid from Riyadh, when he asked about the hadith of istikhara and that it says "if You know," he says this phrase "if You know," while Allah, Glorified and Exalted is He, says He is All-Knowing, All-Aware of everything.

Answer:
He is not doubting Allah's knowledge; he is doubting whether this matter is suitable for him or not suitable for him.
