AHMAD 9497:
from Lammā Ḥaḍar Ramaḍān —
"The Messenger of Allah said: 'There has come to you Ramadan, a blessed month, which Allah, the Mighty and Sublime, has enjoined you to fast. In it the gates of heavens are opened and the gates of Hell are closed, and every devil is chained up. In it Allah has a night which is better than a thousand months; whoever is deprived of its goodness is indeed deprived."' (Using translation from Nasāʾī 2106)

عن لما حضر رمضان —
