Praising God is not for His benefit, but completely for our benefit. We need to always remember that all praise is due to Allah and we need to avoid thinking wrongly to praise any one away from Allah. No bounty but from Allah, so no Praise but to Allah. Prophets and Infallible Imams are praised because they are the most humble servants of Allah, and all Praise is due to Him, so His sincere servants are raised out of His Praise.
Praising Allah (SWT) makes us appreciate the bounties and feel its taste and utilize it in the proper way. Praising Allah (SWT) for His bounties on us makes the bounties remain and increase.
Praising Allah (SWT) makes us humble and avoids us self admiring and misunderstanding ourselves. Praising our Creator makes us think and behave in a realistic way keeping in mind the origin of every good; Allah (SWT).
Praising God in ts real sense makes our life based on the Truth and the noble values.
