Dua is Accepted and Answered While reciting Surah al-Fatihah
The Prophet (salAllahu alayhi wasalam) said that Allah the Exalted had said:
‘ I have divided the prayer into two halves between Me and My servant, and My servant will receive what he asks for. When the servant says: Praise be to Allah, the Lord of the universe, Allah the Most High says: My servant has praised Me. And when he (the servant) says: The Most Compassionate, the Merciful, Allah the Most High says: My servant has lauded Me. When he (the servant) says: Master of the Day of Judgment, He remarks: My servant has glorified Me, and sometimes He will say: My servant entrusted (his affairs) to Me. When he (the worshipper) says: Thee do we worship and of Thee do we ask help, He (Allah) says: This is between Me and My servant, and My servant will receive what he asks for. Then, when he (the worshipper) says: Guide us to the straight path, the path of those to whom Thou hast been Gracious — not of those who have incurred Thy displeasure, nor of those who have gone astray, He (Allah) says: This is for My servant, and My servant will receive what he asks for.
