Imam further explains the matter as following:
When the Prophet reviews your deeds and he sees how many errors and sins there are, how upset and distressed will he be? You do not want the Apostle of God to become upset and distressed; you do not want to break his heart and make him sad.
When he witnesses that the page of your deeds is replete with backbiting, slander and speaking ill of other Muslims and that all your attention was devoted to this worldly and materialistic affairs and that your heart was overflowing with malice, hatred, spite, and suspicion towards each other, it is possible that in the presence of God, the Supreme and Holy, and the angels of Allah, he will be embarrassed that his community and followers were ungrateful for their divine blessings.
And thus unbridled and heedless they betrayed the trust of God, the Holy and Supreme. Someone who is related to us, even if in a menial position, if he errs, we become embarrassed. You are related to the Apostle of Allah, may the peace and blessings of Allah be with him and his progeny; by entering the seminary, you have related yourself to the Law of Islam, the most Noble Apostle and the Noble Qur’an.
If you perform ugly deeds, it upsets the Prophet and he cannot bear it, and God forbid, you may be damned. Do not let the Apostle of Allah, peace be upon him and his progeny, and the pure Imams become upset and saddened. The heart of man is like a mirror, clear and bright, and because of too much attention of this world and too many sins, it becomes dark. However, if a person at least performs the fast for God.
The Almighty, sincerely and without duplicity (I am not saying that other acts of worship are not to be pure; it is necessary for all of the acts of worship to be performed sincerely and without duplicity), then this worship which is a turning away from lust, putting aside pleasure, and cutting oneself off from all but God, if it is performed well in this single month, perhaps the grace of God will be extended to him and the mirror of his heart will be cleaned of its blackness and tarnish.
And there is hope that he will change his ways and become dissuaded from this wilderness and worldly pleasures. When the Night of Power [Laylat al-Qadr] arrives, one will gain the illumination which is obtained on that night by the friends of God and the believers. The reward of such a fast is God, as it has been reported: “The fast is for me and I am its reward.” Nothing else could be the reward of such a fast.
A garden of blessings would not count as a worthy reward for such a fast. If a man takes fasting to mean closing his mouth to food but opening it for backbiting, and in the warm and friendly meetings with company in the nights when there is opportunity and time he engages in backbiting until sahar, such fasting will be of no benefit and have no effect. Rather, one who fasts in this way has not observed the etiquette of the banquet of God.
He has violated the rights of his Benefactor, the Benefactor who has provided him with all the means and conveniences of life before creating him, and has provided for the means of his development. He sent the prophets to guide him. He sent down the heavenly books. Man has been given the power to approach the source of greatness and the light of felicity, has been favored with intellect and perception, and has been the recipient of His generosity.
Now, He has invited His servants to enter His guest house and to sit at the table of His blessings where they are to thank and to praise Him to the extent that their tongues and hands are able. Is it right for the servants who benefit at the table of His blessings and who use the means and conveniences which He has freely provided for them that they should oppose their Master and Host and to rebel against Him?
Is it right that they should use these things in opposition to Him against His wishes? Wouldn’t this be biting the hand that feeds one and the height of ingratitude for man to sit at the table of his Master and with rude and impudent behavior and actions to audaciously insult his honored Host who is his benefactor, performing ugly and evil deeds before the Host?
The guests must at least know who their Host is, and become aware of His dignity. They should be acquainted with the customs and manners of the sessions. They should try not to rebel by performing deeds which conflict with virtue and decorum. The guests of the Supreme Being must come to know the divine station of the presence of the Lord of Majesty.
