OK, a serious question to my fellow Christians: if a Muslim prays for the Pope’s protection, does God hear and answer the prayer because it is His will that His servants be protected, or does God not hear nor answer the prayer because it is misdirected towards Allah, who either doesn’t exist (Isaiah 40), or exists but is demonic (I Corinthians 10) and therefore does not desire the protection of the Pope?
How on EARTH are we to know God's plans, what He hears/doesn't hear and what His opinion is about Allah and/or the Pope?
Since we are NOT privy to our good God's mind, perhaps you only meant it rhetorically.
If a Muslim publically states that he is praying for the Pope’s protection, he is likely employing Taqiyya.
God, of course, does something we will never be able to do: he sees into people's hearts and minds, and He knows their thoughts and their motivations even better than they do, themselves.
So it seems to me there is not just a blanket "yes" or "no" answer to the question, "Does God hear the prayers of Muslims, even or especially when they are praying for the safety of a Christian?"
He knows when their intention is, "I am praying to the One God, the Creator of heaven and earth, of all things visible and invisible, Whoever He may be" --- and that is perfectly plausible even if they say "Allah," since Allah is merely the Arabic word of "God" --- Arabic-speaking Christians were using this word for God for 500+ years before Mohammad was even born. He also knows when their intention is, "I am praying to the 'god' who demands the slaughter of infidels."
He will judge accordingly. With perfect fairness and perfect accuracy. So perfect, that when all things come to light, every good-hearted and fair-minded person on earth will be punching the air and cheering and saying, "He got that exactly right!"
I am the Lord your God, who brought you out of the land of Egypt, out of the house of slavery. You shall have no other gods before me. You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth. You shall not bow down to them or serve them, for I the Lord your God am a jealous God, visiting the iniquity of the fathers on the children to the third and the fourth generation of those who hate me..."
