In the verse I have recited, Allah the Almighty (swt) states, “We have indeed created man in the best of moulds, then do We abase him (to be) the lowest of the low, Except such as believe and do righteous deeds: for they shall have a reward unfailing.” 
The Prophet Muhammad (saw) said in the hadith I have read, “Those who are content with Allah as their Lord, with Islam as their religion, and with Muhammad as their Prophet has found the taste of faith (iman).” 
Islam is a unique system of faith, worship, and morality.
Taking the kalimah al-shahadah by uttering these words is to open the gate to faith, hope, and happiness both for the world and the Hereafter. Those who enter through this gate perform their prayers regularly and meticulously. Prayer (salah) is the pillar of our religion and the light of our hearts. They fast zestfully and patiently. Fasting is the shield protecting us from being captive to our nafs and to Satan. They pay their alms (zakat) sincerely and kindly. Zakat is the bridge turning the ephemeral worldly belongings into eternal gain and brotherhood. They fulfill their duty of hajj devotedly and submissively. Hajj is the holy journey which makes people meet with themselves and other faithful hearts around the Ka’bah.
The aim of worship in Islam is to enable people to establish a sound communication with themselves, with Allah (swt), and with all other beings. For this reason, each worship requires to be completed with good morality. A way of life befitting to Muslims can be lived by observing the moral principles as well as the worships. It is an indispensable requirement of being Muslim to observe the rights, to not let cruelty and oppression, to spread mercy and prevent violence. Making life blessed with justice, honesty, humbleness and generosity is the essential of a Muslim’s personality. Let us not forget that those whose minds are with the truth, whose hearts are with goodness and whose possibilities are with beneficial deeds will fulfill the requirement of their faith.
