salam
We really feel need to praise someone/something when we love them, when we feel happiness through them or need them desperately. It's perfectly natural. We praise Allah because we love Him, His blessings, His help, His company... We are weak, powerless before Him, asking His aid through our sincere prayers. Alhamdulillah, when I'm so depressed, exhausted, words of praise come out of mouth naturally, like "Ya Rahman ya Rahim ya Fattah, you see what i'm going through, have mercy on me. Open my chest and guide me ...." It's all about keeping oneself aware of Allah's greatness.
Like Prophet Ayub (as): "And (remember) Ayyūb (Job), when he called his Lord saying, “Here I am, afflicted by pain and You are the most merciful of all the merciful.” (21:83)"
"The Most Excellent Names belong to God: use them to call on Him, and keep away from those who abuse them- they will be requited for what they do." (7:180)
Think of a prayer without praising Allah, calling His names. Wouldn't it sound dull or artificial ?
All the prophets mentioned in the Quran prayed like this. By glorifying Him, we acknowledge, remember His greatness once again. We become more aware as to how He could solve our issues, repair our broken hearts with His unlimited power. Praising Him with sincere heart reminds us of who we ask for help!
As Zakariyya, (Zechariah) as he called out to his Lord, "Lord! Leave me not out single, (i.e., without offspring) and You are The Most Charitable of inheritors!" (21:89)
Jesus, son of Mary, said, ‘Lord, send down to us a feast from heaven so that we can have a festival- the first and last of us- and a sign from You. Provide for us: You are the best provider.’ (5:114)
He said, "My Lord, forgive me and grant me a kingdom such as will not belong to anyone after me. Indeed, You are the Bestower." (38:35)
"And seek help through patience and prayer, and indeed, it is difficult except for the humbly submissive [to Allah ]" (2:45)
Take care:)
Sorry for my English by the way:)
