Also, noting that you are Christian, I wonder what the Muslims here think about your experience? Why should Eric get help from God instead of you guys, if Eric is praying to the wrong God or doing it in the wrong way?
Let me give you a brief bitesize illustration of Islam;
God is One. No matter what believers in a 'god' or 'gods' call Him, they believe in this 'Supreme Being'.
We believe Allah (arabic word for 'God') is the Supreme being who we should serve and obey,
all other religions serve other created beings as associates with this God. I.e. christians serve
Jesus, who is a slave and creation, and infact an honored Messenger of God. Polytheists serve hand made
idols or
nature. Other people serve their
desires in preference to anything else.
Muslims are the only beings who submit to and serve the Supreme Being alone without associating His creation as partners to Him. This is why they -Muslims- are worthy of His exclusive reward.
On Judgment Day - God will reward those who served Him fully and sincerely.
Anyone who worshipped/served Jesus, or even Muhammad [a creation of God], or
any other human or created object [idol, or themselves etc]
- they will be asked to get their rewards from that object, but that object will not be able to reward them because the objects themselves are created beings - expecting reward or punishment from God.
So true success is in serving the Supreme Being, who is One and the All Able. This is why Islam [submission to God] is the true way sent by God, with
God sending Human Messengers' for centuries and millenia - calling people to serve Him only, calling to strengthening the family ties, helping those who are close to you, and the needy, encouraging the good and forbidding the evil etc.
This is the basic message of Islam, whoever submits in it will find success for his ownself; happiness in this life and the one to come. Whoever rejects it, then he has the choice to - but he will face the consequences of his ungratefulness.
Now
in regards to your question;
God answers the prayers of His creation,
no matter who are what religion they belong to. He even provides for them in this life, no matter what or who they are.
He is so Just - that He will reward those who do good among them in this life accordingly, as a recompense for what they strived for.
If they strived for happiness, He will give them happiness. If they strived for wealth, He will give them wealth. If they strived for pleasure, He will make that path easy for them
. Yet if they were sincere in wanting to follow His guidance, and strived for His pleasure and reward - He would reward them in this life AND the one to come. Since He is able to create endless happiness for His thankful slaves.
So when the disbeliever humbles himself to God and asks of Him, God will provide for them. If only he had asked for goodness in this life and the next, and believed - then he would get goodness in both abodes.
It is all a matter of mind choice , you can pick this world only, or pick both this world and the one to come.
Whatever you strive for - you will get.
Peace.
