“Praise be to Allah, the Cherisher and Sustainer of the worlds”, Allah will say,

“My slave has praised Me.” When the slave says,

“Most Gracious, Most Merciful”, Allah will say,

“My slave has lauded Me.” When the slave says,

“Master of the Day of Judgment”, Allah will say,

“My slave has glorified Me.” When the slave says,

“Thee do we worship, and Thine aid we seek”, Allah will say,

“This is between Me and My slave, and My slave will receive what he asks for.” When the slave says,

“Show us the straight way, the way of those on whom Thou hast bestowed Thy Grace, those whose (portion) is not wrath, and who go not astray”, Allah will say,

This is for My slave, and My slave will receive what he asks for.”
