Be humbly submissive to your Lord!
Allah Almighty restricted the praise exclusively to Himself, and prohibited that one should praise himself. He says:
{...So do not claim purity for yourselves...}
[Surat an - Najm: 32]
Our Lord praises Himself to introduce Himself to us and so that we can turn to Him through praise and hope to receive His forgiveness, bounty, and Paradise.
What a Generous Lord! He guides us to perform good deeds and then appreciates that, and rewards us for it.
{...They will be called, “This is Paradise that you are made to inherit for what you used to do.”}
[Surat al-A‘rāf: 43]
When our Lord wants to make His bounty manifest upon us, He creates it and attributes it to us.
For example, He gives you money, and you spend out of it in charity, and then He appreciates your charity, though the money originally belongs to Him!Out of His kindness, Allah Almighty laid down various forms of praise, so that we know how to praise Him in the best manner.
He says:
{All praise be to Allah, the Lord of the worlds.}[Surat al-Fātihah: 2]
He also says:
{All praise be to Allah Who created the heavens and earth, and made darkness and light...}
[Surat al-An‘ām: 1]
