It has been narrated from the Commander of the Faithful Imam 'Ali [a] that:
"Don't say Ramadhan because, you don't know what Ramadhan is. Whoever says so must pay charity and must offer an atonement fast, instead of saying Ramadhan, say the way Allah has called it the Month of Ramadhan."
The most important duty of a devoted wayfarer in this great month is to understand the right of this Holy Month in which Allah (the Glorious, the Exalted), has invited the wayfarers of His path for a feast. Also he must understand the correct meanings of fasting and its relevance with Allah's invitation. Having discovered this reality he must endeavour that all his actions and deeds are accompanied with required devotion and sincerity in order to earn the pleasure of his host Allah (the Glorious, the Exalted).
 The Commander of the Faithful 'Ali ibn Abu Talib [a]: was the first perfect exemplar of the teachings of the Most Noble Messenger [s]. 'Ali was raised by him from early childhood and followed him like a shadow until the very end of the latter's life. He was like a moth before the prophetic flame; the final moment when he was separated from the Most Noble Messenger [s] was when he embraced his corpse and laid it to rest. 'Ali [a] was the first person after the Most Noble Messenger [s] to approach spiritual realities in the manner of philosophical reflection, that is, by free exercise of reason. He used many technical terms and laid out and organized the rules of Arabic grammar in order to protect the Holy Qur'an from copyist's errors. The exact scholarship, spiritual culture, and consideration of ethical, social, political, and even mathematical problems shown in 'Ali's [a] discourses, letters, and other documents that have reached us are astonishing. The wealth of these documents makes 'Ali [a] the best known individual among Muslims to have a full realization of the sublime goals of the Holy Qur'an and the critical and practical concepts of Islam as they should be realized. They testify to the soundness of the prophetic saying: "I am the city of knowledge, and 'Ali is its gate." Furthermore, he combined this knowledge with action. In short, 'Ali's outstanding character is beyond description, and his virtues are innumerable. Never in history has someone's character drawn the attention of the world's scholars and thinkers to such an extent [Tr].
