There is a sense in which the whole practice of Islam is, in one form or another, dhikr: the remembrance of God. There are reasons for believing, too, that this unceasing invocation on the part of the Muslim community provides all humanity with benefits which are incomparably preferable to those of "progress" or "development," and which, should it ever be silenced, would in all probability signal the destruction of the world.

—Roger Du Pasquier in "Unveiling Islam"

The Prophet (peace and blessings be upon him) said, “Ramadan is a blessed month that has come to you, during which Allah has made it obligatory for you to Fast. During the month,?the gates of Heaven are opened, the gates of Hellfire are locked, and the rebellious devils are chained. In it Allah has a night which is better than a thousand months. He who is deprived of its good has indeed suffered deprivation.”

The Prophet (peace and blessings be upon him) said, “Whoever fasts in the month of Ramadan out of sincere faith, and hoping for a reward from Allah, then all his previous sins will be forgiven.”

It might be said that the environmental crisis, as well as the psychological unbalance of so many men and women in the modern world, the ugliness of the urban environment and the like, are the results of the attempt of man to live by bread alone and announce his independence from Heaven. But man cannot escape the effect of his actions, which are themselves the fruit of his present state of being.

"La ilaha illa'llah" (no god but God): A phrase sublime in its meaning, brief in its construction, vast in its effect, noble in its rank, brilliant in its light, and unique in its merit. It comprises four words upon which the Faith is founded. This is the phrase that was given in every Book sent down by God to every one of His noble Messengers, and through which one is rescued from the Fire and wins eternal happiness in the Garden.

A skeptic came to Imam al-Shafi'i (God have mercy on him) and asked, "What is your proof for the existence of God?" The Imam replied, "The Mulberry leaf has a single taste, a single color, a single fragrance and a single shape. However, when the silk worm eats it, she produces silk. When the bee eats it, he produces honey. When the ewe eats it, she becomes plump and her milk becomes abundant. When the gazelle eats it, it nourishes him and mixes with his blood producing musk. Who is the one who has made these various processes and products from a single food? Surely it is God?” (As related and translated by Imam Zaid Shakir.)

O you who believe, fear God and speak uprightly. He will set aright for you your works and will forgive you your sins. He who obeys God and His Messenger has attained supreme triumph. (Quran, 33:70-71)

And tell My servants that they should speak only what is good, for Satan stirs discord between them. Indeed, Satan is to man a manifest enemy. (Quran, 17:53)

And when you speak, be just, even though it may be against a kinsman; and fulfill the pact of God. This He enjoins upon you that you may remember. (Quran, 6:152)

"Our indebtedness to Muslim culture is extraordinary. Try doing your finances using Roman instead of Arabic numerals, and you'll get the idea. Have you had your coffee? The attempt 400 years ago to prohibit Christians from drinking coffee because it was a Muslim drink obviously has failed. Thomas Aquinas, for centuries the pre-eminent Christian theologian, was influenced by Muslim philosopher Ibn Rushd (Averroes). Renaissance art, music and poetry, out of which today's world developed, were stimulated by encounters with Muslim thinkers."

"When intelligence is complete, then speech becomes rare" -- Ali Ibn Abi Talib

"When a person's intelligence is complete, his speech becomes infrequent. Be sure of the stupidity of a man if he speaks too much....Speech is a necessary evil, but silence is salvation. So when you have to talk, do not be prolific. You will never once repent of your silence, but oftentimes you will repent of your speech". -- Imam al-Zarnuji

"Among His signs are the night and the day, and the sun and the moon. Do not bow to the sun and the moon, but bow to God who created them, if you truly worship Him. If they show arrogance, those who are in God's presence glorify Him night and day, and never are they wearied. And among His signs is that you see the earth still. Then when We shower down water on it, it stirs and swells . Surely He who gives it life will resurrect the dead. He has power over all things". Quran, 41:37-39
