It was narrated on the authority of Abu Hurayrah, may Allah be pleased with him, that the Messenger of Allah said: “When the month of Ramadan starts, the gates of Heaven are opened and the gates of Hell are closed and the devils are chained.” [Al-Bukhari and Muslim]

In a third version, the Prophet gave glad tidings to his Companions, saying: “There has come to you Ramadan, a blessed month. Allah has made it obligatory for you to fast in it. In this month, the gates of Heaven are opened and the gates of Hell are locked, and the rebellious devils are chained up. In it there is a night that is better than a thousand months, and whoever is deprived of its goodness is deprived indeed.” [An-Nasaa’i and Ahmad]

It was narrated that Abu Hurayrah and Abu Sa‘eed, may Allah be pleased with them, said that the Messenger of Allah said: “Allah has people whom He saves (from Hell) every day and night (in Ramadan) and every one of them has a supplication that will, indeed, be fulfilled.” [Ahmad and At-Tabaraani: authentic chain of narrators]

It was narrated on the authority of Jaabir, may Allah be pleased with him, that the Messenger of Allah said: “Allah has people whom He saves (from Hell) at each time of Iftaar (breaking tha fast), and that is every night (of Ramadan).” [Ibn Maajah] [Al-Albaani: Hasan Saheeh[

• First: The virtues of the month of Ramadan, where great things take place, such as opening the gates of Paradise, closing the gates of Hell and chaining the devils. All this takes place in the first night of Ramadan and continues to the end of the month.
• Second: The first Hadeeth indicates that Paradise and Hell are already created and that their gates are actually opened and closed.
• Third: Seasons with a special virtue and the righteous deeds that are observed therein bring about the Pleasure of Allah and this results in opening the gates of Paradise and closing the gates of Hell.
• Fourth: It is permissible under Sharee‘ah (Islamic legislation) to give glad tidings about the advent of Ramadan and congratulate people on living to witness it. The Prophet used to remind his Companions of such merits to make them rejoice and drive them to do righteous deeds. Thus, glad tidings should be given with regard to every good thing.
• Fifth: Rebellious devils are chained in Ramadan and thus their effect on people is weakened due to the good deeds that people do.
• Sixth: Allah The Almighty confers His favor and kindness upon His slaves by preserving their fasting and warding the harm of rebellious devils off them, so as not to spoil their acts of worship in the blessed month of Ramadan.
• Seventh: Proving the existence of devils and that they have bodies that can be chained and that rebellious devils from among them are chained during the month of Ramadan.
• Eighth: These great advantages, which are unique to Ramadan, are enjoyed by the believers who glorify this month and fulfill the rights of Allah The Almighty during it. However, the disbelievers who do not fast during this month and do not believe in its sanctity, the gates of Paradise will not be opened for them, the gates of Hell will not be closed for their sake, their devils will not be chained and they will not deserve to be saved from Hell. Consequently, anyone of them who dies during the month of Ramadan or during any other month will deserve the punishment of Allah and will certainly taste it.
• Ninth: It is feared that Muslims who imitate the disbelievers in violating the sanctity of Ramadan, breaking the fast during the daytime, committing acts that invalidate their fasting or decrease its reward (such as backbiting, carrying tales or spreading slander and attending gatherings where such acts take place), will be excluded from this great favor from Allah; the gates of Paradise will be closed for them, the gates of Hell will be opened for them and their devils will be released.
• Tenth: The opening of the gates of Paradise and the closing of the gates of Hell do not contradict the verse (which means): {Gardens of perpetual residence, whose doors will be opened to them.} [Quran 38:50]

• Eleventh: The virtue of the Night of Al-Qadr and how it is better than one thousand months. The Muslim who misses that night is deprived of a great blessing.
• Twelfth: Allah The Almighty saves people from Hell every night in the month of Ramadan. Those who are worthier of redemption are those who fast perfectly, pray Qiyaam (supererogatory night prayers) well, perform a lot of righteous deeds, out of loving Allah and hoping for His reward and fearing His punishment.
• Thirteenth: Those people who will be saved from Hell will be granted the privilege of having their supplications fulfilled. Thus, Allah combines two great rewards for them: redemption from Hell and answering their supplication.
• Fourteenth: The fasting Muslim should not commit anything that invalidates his fasting or decreases his reward. Also, he should keep his hearing, sight and tongue away from everything that has been forbidden by Allah, to be saved from Hell.
• Fifteenth: The fasting Muslim should frequently supplicate Allah The Almighty, because the supplication made by a fasting person is fulfilled, by the will of Allah The Almighty.
