A person should pause a little at the end of each ayah he recites from al-Fatihah to wait for the response from his Lord; as if he is waiting to hear Him to say, “My slave has praised Me” when he recites; “All Praises and thanks are due to Allah, the Lord of all Worlds,” and “My slave has extolled me” after reciting; “The Most Gracious (Ar-Rahman), The Most Merciful (Ar-Rahim)” and “My slave has glorified Me” after reciting; “Master of the Day of Judgment” and “This is between Me and My slave and My slave shall have what he requested” after reciting; “You Alone we worship and You Alone we ask for help.” Only the one who has experienced the true taste and sweetness of salah can realise that no other statement could ever replace the takbir and al-Fatihah in salah, just as how no acts can ever replace the standing, bowing down, and prostration in salah. This is because each act and each statement in salah has a unique effect and compromises a distinctive experience, besides its representation of the worshipper’s servitude to Allah.
The statement of Allah; “All praises and thanks are due to Allah, the Lord of the Worlds.” confirms the perfection of Allah’s Names and Attributes, and declares His transcendence above every defect and shortcoming, be it in respect to His names, Attributes or Actions. All His Actions comprise Wisdom, Mercy, Justice and benefit, and all His Attributes are Perfect and Lauded, and all His Names are Supreme and Beautiful.
