The blessed month of Ramadhān is a month of blessings, mercy and forgiveness. This sacred month will pass without us realising what valuable and precious moments were wasted. What has gone cannot come back, and what has been lost cannot be re-acquired. For one who wishes to acquire the pleasure of Allāh ta'ālā, even one moment is sufficient.
Rasūlullāh sallallāhu 'alayhi wasallam has said in a hadīth that, "Ramadhān is a month the beginning of which is mercy, the middle of which is forgiveness and the end of which is deliverance from the Fire of Jahannam." (Ibn Khuzaymah)
From the first of Ramadhān, the Mercy of Allāh ta'ālā descends upon those very pious servants who have no sins in their book of deeds. As far as the sinners are concerned, they are of two types: sinners of a lesser degree, and those who are so filthy that were they to die in their present condition they would go straight into the Fire of Jahannam.
As far as the sinners of a lesser degree are concerned, their sins are forgiven after their striving for 10 days. Upon seeing their hard work and effort, Allāh ta'ālā showers His Forgiveness upon them at the end of the first 10 days. For those filthy with sins upon whom Jahannam was wajib (incumbent), after working hard for 20 days, the Forgiveness of Allāh ta'ālā enshrouds them and they are then granted deliverance from the Fire of Jahannam. How merciful is Allāh ta'ālā!
We ask Allāh ta'ālā that He grant us Jannah-al-Firdaws with His eternal Pleasure and save us from the Fire of Jahannam. Āmīn.
