لْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ

All praises be to Allāh, the Lord of the worlds (for His perfect attributes and benevolent and just actions).
[Al-Fātiḥah, 1:1]

Imām Muḥammad ibn Jaʿfar al-Ṭabarī [d. 310 AH] said:

The meaning of ‘All praises be to Allāh’ is: All gratitude is sincerely for Allāh, Exalted in praise, besides all that is worshipped in His stead, and besides what is put forth by His creation. For He has bestowed on His servants bounties above enumeration, the true number of which cannot be fully comprehended by any being save for Him. He is the One who has made the faculties [of His slaves] amenable to His obedience, facilitated the execution of that which has been made obligatory by those carriers of responsibility [answerable muslim men and woman]. In addition to what He has stretched forth for them from provision and nourished them from bountiful living. All without them having carried out anything that would make them deserving [of such bounties]. In addition to what he has informed them concerning, and called them towards, from the means by which they are able to achieve everlasting life in the most stationary of homes in the enjoyment of eternal bounty [i.e in the hereafter]. Thus, all praise be to our Lord for all of this, at our beginning and at our end.
