"Were they created by nothing, or were they themselves the creators?
Or did they create the heavens and the earth?
Nay, they have no firm belief.”
[Holy Qur'an: 52:35-36]
Rasul Allah, sal Allah alayhi wa sallam, said, "A believer may achieve the status of one who fasts during the day regularly and spends the night regularly in prayer: through his good manners."
