3 – This remembrance is supremely appropriate, for it embodies humility and imploring Allah, exalting Him above every deficiency and blemish, affirming all praise to Him, and then—after all that—asking His forgiveness, all while the servant is at the peak of submission and lowliness before his Lord, bowing and prostrating.
4 – The remembrance in question is recommended, not obligatory. What the Law has established by unanimous agreement is to say “subḥāna rabbī al-ʿaẓīm” during bowing and “subḥāna rabbī al-aʿlā” during prostration. Muslim and the Sunan collections record from Ḥudhayfah that he prayed with the Prophet ﷺ, and the Prophet ﷺ would say in his bowing, “subḥāna rabbī al-ʿaẓīm,” and in his prostration, “subḥāna rabbī al-aʿlā.”
5 – This report directs the heart to the attributes of Allah—the One of power, dominion, and majesty. Such reflection leads the servant to perfect trust and reliance upon Him: he seeks refuge with no one else, pays heed to no one else, and magnifies no one else. Every matter is lightened for him because he beholds the power of a Mighty, Capable Lord from Whom he draws help and success, and upon Whom he depends to attain the good, strength, and happiness he desires.
