The month of Ramadān is the month of serenity and purity [shahr as-safā’], the month of fulfillment and fidelity [shahr al-wafā’]. It is the month of those who practice the remembrance of their Lord [shahr adh-dhākirīn], the month of those who endure with patience [shahr as-sabirīn], and the month of those who are honest and truthful [shahr as-sadiqīn]. So, if it does not have the effect of improving your heart — if it does not induce you to desist from the rebellious acts against your Lord, and does not make you avoid the company of troublemakers and criminals — what else can exert a positive influence on your heart? What goodness can be hoped for in a case like yours? What redeeming quality can survive in someone like you? What successful outcome can be expected from an individual like you?

You had better pay attention, O miserable wretch, and try to learn from what has happened to you. Come to your senses, wake up from your slumber, shake off your heedless indifference, and take a good hard look at what has befallen you. However little of the month you still have left, you must seize every opportunity for repentance [tawba] and contrition [ināba]. Take full advantage of the time that is still available for seeking forgiveness [istighfār] and practicing worshipful obedience [tā’a]. If you follow this advice, you may yet be one of those who receive the blessings of mercy [rahma] an compassionate grace [ra’fa].

Then, when the month of Ramadān comes to its close, you should bid it farewell with the shedding of copious tears. You should weep over your unfortunate self, while moaning and wailing and uttering plaintive cries of lamentation. For, as you must be well aware, many a keeper of the fast [sā’im] will never keep another fast, and many a keeper of the vigil [qā’im] will never keep vigil again.

The worker will be paid his wages, once he has finished his work, and we have now finished the work [required of us in the month of Ramadan]. But if only I knew for certain whether our fasting [siyām] and our vigil [qiyām] have been accepted, or whether they be used to slap us in our faces! If only I knew for certain which of us has been accepted, so that we may congratulate him, and which of us has been rejected, so that we may offer him our condolences!

The Prophet (Allah bless him and give him peace) once said:

There is many a one who keeps the fast by day, yet who gets nothing out of his fasting but hunger and thirst. And there is many a one who spends the night in vigil and prayer, yet who gets nothing from his vigil other than insomnia.

The Messenger of Allah (Allah bless him and give him peace) also said that on the final night of the month everyone would be forgiven. His Companions asked if this night was Laylat al-Qadr.

He replied:

No, do you not see that when workers finish their work they are paid their wages in full?’
