Practices of Submission (Islam)
In the name of GOD, Most Gracious, Most Merciful

Successful indeed is the one who redeems his soul. By remembering the name of his Lord and observing the contact prayers (Salat). [87:14-15]
who believe in the unseen, observe the Contact Prayers (Salat), and from our provisions to them, they give to charity. And they believe in what was revealed to you, and in what was revealed before you, and with regard to the Hereafter, they are absolutely certain. These are guided by their Lord; these are the winners. [2:3-5]
The religious duties instituted by God are in fact a great gift from Him. They constitute the nourishment required for the growth and development of our Souls. Without such nourishment, we cannot survive the immense energy associated with God's physical presence on the Day of Judgment.
Belief in God does not by itself guarantee our redemption; we must also nourish our souls (6:158, 10:90-92). Additionally, 15:99 states that observing the religious duties instituted by God is our means of attaining certainty: "Worship your Lord in order to attain certainty."
Requirements of the Test
[6:158] Are they waiting for the angels to come to them, or your Lord, or some physical manifestations of your Lord? The day this happens, no soul will benefit from believing if it did not believe before that, and did not reap the benefits of belief by leading a righteous life.* Say, "Keep on waiting; we too are waiting."
[10:90] We delivered the Children of Israel across the sea. Pharaoh and his troops pursued them, aggressively and sinfully. When drowning became a reality for him, he said, "I believe that there is no god except the One in whom the Children of Israel have believed; I am a submitter."
[10:91] "Too late!* For you have rebelled already, and chose to be a transgressor.
Pharaoh's Body Preserved*
[10:92] "Today, we will preserve your body, to set you up as a lesson for future generations."* Unfortunately, many people are totally oblivious to our signs.
[15:99] And worship your Lord, in order to attain certainty.*

Of course, there is a lot more one can do to remember God and grow our souls. We encourage you to read the Quran to find out more.
[2:177] Righteousness is not turning your faces towards the east or the west. Righteous are those who believe in GOD, the Last Day, the angels, the scripture, and the prophets; and they give the money, cheerfully, to the relatives, the orphans, the needy, the traveling alien, the beggars, and to free the slaves; and they observe the Contact Prayers (Salat) and give the obligatory charity (Zakat); and they keep their word whenever they make a promise; and they steadfastly persevere in the face of persecution, hardship, and war. These are the truthful; these are the righteous.
