From now on...
From now on, keep your tongue from backbiting, slander, speaking bad, and lies, and expel from your hearts all spite, envy, and other ugly satanic attributes. If you are able, cut yourself off from all but Allah. Perform your deeds sincerely and without duplicity. Cut yourselves off from the Satans among humans and the jinn, although we ourselves apparently cannot aspire to reaching such a valuable state of felicity. At least try to see to it that your fast is not accompanied by sin.
Otherwise, even if your fast is correct from the point of view of Islamic law, it will not ascend to be accepted by God. There is a big difference between the ascension of one’s works and their acceptance on the one hand, and their religious correctness on the other.
If, by the end of the blessed month of Ramadan, there is no change in your works and deeds, and your ways and manners are no different than they were before the month of fasting, it is evident that the fast which you were expected to perform was not realized, and that which you have done is no more than a vulgar physical fast.
In this noble month, in which you have been invited to the divine banquet, if you do not gain insight [ ma‘rifat ] about God the Almighty nor insight into yourself, it means that you have not properly participated in the feast of Allah. You must not forget that in this blessed month, which is the ‘month of Allah’, in which the way of divine mercy is opened to the servants of God and the satans and devils, according to some reports, are locked in chains.
[^4] If you are not able to reform and refine yourselves, and to manage and control your nafs al-ammarah [the commanding soul], [^5] to subdue your selfish lusts and to cut off your relations and interests with this world and material things, then after the end of the month of fasting it will be difficult for you to be able to accomplish this. Therefore, take advantage of this opportunity before the magnificent grace of it vanishes, and purify and reform yourselves.
Get ready and prepare to perform the duties of the month of fasting. Let it not be that prior to the arrival of the month of Ramadan you are like one who is wound up by the hand of Satan so that in this single month when the satans are enchained you automatically busy yourselves with sin and deeds opposed to the orders of Islam!
