Ramadan Mubarak!!
The Messenger of Allah(ﷺ) used to give good news to his Companions with the arrival of Ramadan, he(ﷺ) would say:
"There has come to you Ramadan, a blessed month...
Allah has made it obligatory on you to fast (this month).
During it the gates of Paradise are opened and the gates of Hell are locked, and the 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."
"Ref:al-Nisaa'i, 4/129; Saheeh al-Targheeb, 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!"
"Ref: Lata'if al-Ma'arif, (1/158) | Translated by Abbas Abu Yahya Miraath al-Anbiyya]"
Ramadan Mubarak!! May we all have a very blessed Ramadan :) Ameen!
