Prayers are a one and last way for God happiness.
It is the first pillar of Islam that the Prophet may God praise him, mentioned after mentioning the Testimony of Faith, by which one becomes a Muslim. It was made obligatory upon all the prophets and for all peoples. God has declared its obligatory status under majestic circumstances. For example, when God spoke directly to Moses, He said,
“And I have chosen you, so listen to that which is inspired to you. Verily, I am God! There is none worthy of worship but I, so worship Me and offer prayer perfectly for My remembrance.” (Quran 20:13-14)
I like so much these beautiful lines.
