A man narrated [a story] to me, that in their town there was a blind man who knew the time of Fajr had arrived [just] by the smell [in the air]; yes, [just] by its smell – without actually [being able to] see it!
Missing the Fajr prayer and sleeping during its time instead of praying it, is from the greatest of the prohibited acts, and from the acts of the hypocrites.
Abu Bakr al-Anbaaree said that al-Imaam, al-Haafith Abu ‘Ubayd would divide the night into thirds; so he would pray a third of it, and sleep a third of it, and author books [during] a third of it.
Whoever sleeps and misses the prayer, and thereafter prays after its time has passed – would it be accepted [from him]?
If a man or woman are in a state of janaabah at the time for bed, and they want to sleep, how should they utter the [words of] remembrance for sleep as it is comprised of verses [of the Qur.aan] and supplications?
