In Islamic Sharia, fasting means, with intention (niyyat), to abstain from food and drink and marital relations from the beginning of dawn until sunset, in obedience to the command of Allah. The month of Ramadan is a month of immense importance for the Muslim Ummah.
Ramadan (Arabic: رمضان Ramaḍān, [variations] Persian: رَمَضان Ramazān; Urdu: رَمْضان Ramzān; Turkish: Ramazan) is the ninth month of the Islamic calendar, in which Muslims worldwide observe the Islamic fast, Saum. Observing the fast in the month of Ramadan is the third of the five pillars of Islam.
The importance and virtues of Ramadan are:-
The beloved Prophet Rasulullah Sallallahu Alaihi wa Sallam said: Allah Ta'ala declares, “Every deed of the children of Adam is for himself, except fasting; fasting is for Me, and I Myself will give its reward. Fasting (to save oneself from the punishment of Jahannam) is a shield. Let none of you, while fasting, become engaged in obscene talk and quarrelsome behavior. If anyone abuses him or quarrels with him, let him simply say: I am fasting. By Him in Whose hand is the life of Muhammad, the smell from the mouth of a fasting person is more pleasant to Allah than the fragrance of musk. The fasting person has two joys: one when he breaks his fast, and the other when he meets his Lord.” (Bukhari)
Hazrat Abdullah Ibn Amr (RA) narrated that Rasulullah Sallallahu Alaihi wa Sallam said: “Fasting and the Quran will intercede for the servant on the Day of Resurrection before Allah. Fasting will say: O my Lord! I kept him from food and desires during the day (of Ramadan), so accept my intercession on his behalf. The Quran will say: I kept him from sleep at night, so accept my intercession on his behalf. Therefore, the intercession of both will be accepted (and he will be admitted to Paradise).” (Baihaqi)
Hazrat Abu Hurairah (RA) said: Rasulullah Sallallahu Alaihi wa Sallam said: “When the first night of Ramadan comes, the satans and rebellious jinn are chained. The gates of Hell are closed, and none of its gates is left open. The gates of Paradise are opened, and none of its gates is closed. A herald calls out in this month: O seeker of good! Come forward. O seeker of evil! Desist. Allah Ta'ala frees many persons from Hell in this month, and this happens every night.” (Tirmidhi and Ibn Majah). Hazrat Ibn Abbas (RA) said: “When the month of Ramadan began, Rasulullah Sallallahu Alaihi wa Sallam freed all the prisoners and gave charity to every beggar.” (Baihaqi)
The famous Hadith scholar Hazrat Abu Hurairah (RA) narrated that Rasulullah Sallallahu Alaihi wa Sallam said: “Whoever observes the fast in the month of Ramadan out of faith and in hope of reward, his previous sins will be forgiven. Whoever stands in prayer during the nights of the month of Ramadan out of faith and in hope of reward, his previous sins will be forgiven. Whoever spends the Night of Qadr in prayer out of faith and in hope of reward, his previous sins will be forgiven.” (Bukhari, Muslim)
