It was narrated that Abu Hurairah said, 'I heard the Messenger of Allahﷺ say':
"Allah said: 'I have divided the prayer between Myself and My slave into two halves, and My slave shall have what he has asked for.'When the slave says: 'Al-hamdulillah i rabbil Alameen (All the praise is to Allah, the Lord of all that exists),' Allah says:'My slave has praised Me, and My slave shall have what he has asked for.' And when he says: 'Ar-Rahmanir-Rahim (The Mos Gracious, the Most Merciful),' Allah says: 'My slave has extolled Me, and My slave shall have what he has asked for.' And when he says: 'Maliki yawmiddin [The Only Owner (and he Ruling Judge] if the Day of Recompense],' Allahs says: 'My slave has Glorified Me. This is for Me, and this Verse is between me and My slave in two halves.' And when he says: ' Iyyaka na'budu wa iyyaka nastain [You (Alone) we worship, and You (Alone) we ask for help],' He says: 'This is between Me an My slave, and My slave shall have what he has asked for.' And the end of the Surah is for My slave.' And when he says: 'Ihdinas-siratal-mustaqeema, siratal-alldhina an'amta alayhim a lad-dallin [Guide us to the Straight Way, the way of those on whom You have bestowed Your Grace, not(the way) of those who earned Your Anger, nor of those who went astray],' He says: 'THis is for My slave, and My slave shall have what he has asked for."
