at-Tirmidhī, Ibn Mājah and Ibn Khuzaymah narrated in one report:
“When the first night of the month of Ramaḍān comes, the devils and rebellious Jinn are chained up and the gates of Hell are closed, and not one gate of it is opened. The gates of Paradise are opened and not one gate of it is closed. And a caller cries out:
يا باغي الخير أقبل ، ويا باغي الشر أقصر ، ولله عتقاء من النار وذلك كل ليلة
‘O seeker of good, proceed (come forth!!); O seeker of evil, desist. And Allāh has those whom He redeems from the Fire, and that happens every night.”
[صحيح الجامع ٧٥٩ ، وحسنه الألباني]
From Abu Hurairah [رضي الله عنه] who said: The Messenger of Allaah [ﷺ] used to give good news to his Companions with the arrival of Ramadan, he would say:
«قد جاءكم شهر رمضان شهرٌ مبارك ، كتب الله عليكم صيامه ،فيه تفتح أبواب الجنة وتغلق فيه أبواب الجحيم ، وتغل فيه الشياطين ، فيه ليلةٌ خيرٌ من ألف شهر ، من حُرِمَ خيرها فقد حُرِم.»
❝Indeed the month of Ramadan has arrived, a blessed month. Allaah has prescribed fasting for you. In this month the doors of Paradise are opened and the doors of hell are closed. The devils are shackled. In Ramadan there is a night better than a thousand months, whoever is prohibited from the good in that night then indeed he has been prohibited from good.❞
[Collected By al-Mundhari In Targheeb Wa Tarheeb | Authenticated By Albaani, (1/490)]
Ibn Rajab al-Hanbali said:
❝Some of the scholars said: This hadeeth is a foundation for some people congratulating others with the month of Ramadan.
How can one not give good news to the believer with the doors of Paradise opening.
How can one not give good news to the sinful that the doors of the Hell fire have been closed.
How can one not give good news to the intelligent one with that the devils are shackled.
Where can this time period be compared to any other time.❞
[Lata’if al-Ma’arif, (1/158)]
