The revered religion of Islam is in fact a system supplied with beliefs, morals and practical matters. Religious faith in Islam consists of joining up of the heart with God and belief in the Day of Judgment; the angels; the Prophets and the Glorious Quran. Morality in Islam consists of humbleness; humility; etiquette; patience; submissiveness; fortitude; tolerance; perseverance; kindness; compassion; good will; having mild disposition; chastity and sincerity; justice, helpfulness; and generosity. Action in Islam consists of prayer; fasting; the Hajj(the Holy pilgrimage to Mecca); paying alms and the one fifth levy; enjoining the good and forbidding the evil; Jihad[1]; taking God as a friend and dissociation from evil; being good to one's parents; and observing the rights of those whom one encounters.
Of course, the three above-mentioned matters are not all the matters of Islam, but rather examples of the perfect, comprehensive, universal religion of Islam which is responsible - in all of life's affairs - for the welfare of people in this world and in the Hereafter. Actually, religion is the sun and guiding light in life; the guide towards God; and the improver of man in this world and in the Hereafter. There is no worthier jewel in the treasury of God's Creation than religion: the religion propagated by all the Prophets, the Imams, the Saints. It is the religion in which whoever becomes adorned with, puts on a semblance of God, having opened up all the doors of prosperity to himself. Whoever keeps his distance from Islam will have opened all the doors of misfortune for himself.
Religion and piety hold the same worth before God. Beautifying one's self with God's religion results in the best person, the most outstanding creature and an incomparable or matchless living being in Creation.
Those who have faith and do righteous deeds, they are the best of the creatures. [Holy Quran: Baiyina 98:7]
If one adorns himself with the attributes of a believer mentioned in the Glorious Quran and religious traditions, this will result in an acceptable believer expressed in the following terms: "being humble in prayer; protesting against false and futile talk; paying the alms tax; protecting the private parts of the body from forbidden acts; protecting whatever has been entrusted to you; keeping one's promise or oath and guarding one's prayers."
Those who humble themselves in their prayers; who avoid vain talk; who are active in deeds of charity; who abstain from sex except with those joined to them in the marriage bond, or (the captives) whom their right hands possess, - for (in their case) they are free from blame, but those whose desires exceed those limits are transgressors; - those who faithfully observe their trusts and their covenants; and who (strictly) guard their prayers; [Holy Quran: Muminun 23:2-9]
We may add the following : being humble on earth; encountering the ignorant with a healthy mind; spending the night in prostration and standing; praying for being saved from the Wrath; not being extravagant when helping the needy; avoiding envy; being moderate; avoiding association of other gods to be partners with God; murder and fornication; avoiding false, oppressive witnessing; forgiving vain talk through nobility; taking a good look at God's signs; praying for the wife and the children; and praying to lead the righteous.
Those who spend the night in adoration of their Lord prostrate and standing; those who say, "Our Lord! avert from us the Wrath of Hell, for its Wrath is indeed an affliction grievous, - evil indeed is it as an abode, and as a place to rest in"; those who, when they spend, are not extravagant and not niggardly, but hold a just (balance) between those (extremes); those who invoke not, with God, any other god, nor slay such life as God has made sacred, except for just cause, nor commit fornication; - and any that does this (not only) meets punishment (but) the Penalty on the Day of Judgment will be doubles to him, and he will dwell therein in ignominy.- unless he repents, believes, and works righteous deeds, for God will change the evil of such persons into good, and God is Oft-Forgiving, Most Merciful, and whoever repents and does good has truly turned to God with an (acceptable) conversion;- those who witness no falsehood, and, if they pass by futility, they pass by it with honorable (avoidance); those who, when they are admonished with the Signs of their Lord, droop not down at them as if they were deaf or blind; and those who pray, "Our Lord! Grant unto us wives and offspring who will be the comfort of our eyes, and give us (the grace) to lead the righteous. [Holy Quran: Furqan 25:64-74]
The Commander of the Faithful (Imam Ali) stated: Among the characteristics of a believer we can state that he is not attached to financial affairs; his efforts are mainly geared to religiousness; his nobility is in contentment; and his efforts are for the Hereafter. His good deeds are increased; his ranks are elevated; and he is approaching deliverance and prosperity. [Mizan al-Hikmat, v.1, p.333]
He also said: A believer is one who is continually remembering God; thinks a lot; is thankful for all the blessings; and perseveres in the face of hardships. [Ibid]
Imam Sadiq (Pbuh) said: A believer is one whose total income is legitimately earned; is good-tempered; is not deceitful; donates some of his extra income; and avoids excessive talk. [Bihar al-Anwar, v.67, p.293]
We can see the following points in the traditions regarding the worth of the believers. Imam Sadiq (Pbuh) has been narrated as having said:
A believer's honor and respect is greater than that of the Ka'ba. [Mizan al-Hikmat, v.1, p.330]
The fifth Imam (Pbuh) said:
A believer is well-known in the Heavens in the same manner that a man knows his wife and children. And verily a believer is closer to God than the Archangel. [Ibid]
The Prophet (Pbuh) said: God, Majestic is His Praise, says: I swear by My Honor and Majesty that I have not created any creature among My Creation that is dearer than a believer. [Bihar al-Anwar, v.71, p.158]
