When you say Allahu Akbar, Subhan Allah, Al hamdulillah, La ilaha ila Allah, you are glorifying your Lord.
“Therefore remember Me (by praying, glorifying). I will remember you.” Quran(2:152)
“And remember Allah much, that you may be successful.” Quran(62:10)
Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (sallallaahu ’alayhi wa sallam) said, “The uttering of the words: “Subhan-Allah (Allah is free from imperfection), Al-hamdu lillah (all praise is due to Allah), La ilaha illallah (there is no true god except Allah) and Allahu Akbar (Allah is the Greatest)’ is dearer to me than anything over which the sun rises.”Muslim
There is a hadith which say: “Whoever glorifies Allaah (says Subhaan Allaah) thirty-three times immediately after each prayer, and praises Allaah (says Al-hamdu Lillaah) thirty-three times, and magnifies Allaah (says Allaahu akbar) thirty-three times, this makes ninety-nine, then to complete one hundred says Laa ilaaha ill-Allaah wahdahu laa shareeka lahu, lahu’l-mulk wa lahu’l-hamd wa huwa ‘ala kulli shay’in qadeer (There is no god except Allaah Alone, with no partner, His is the power and His is the praise, and He is Able to do all things) – his sins will be forgiven even if they are like the foam of the sea.” (Reported by Muslim, 939).
