The Spider - 29:45
Read from the Book which We have revealed to you and observe the prayer. For prayer discourages from abominable and evil things. The remembrance of Allah (through prayer) is most important. Allah knows what you do.
Prayer discourages disgusting and evil things:
Prophet Hud/11:87
"They said: "Shu´ayb, does your prayer require us to give up what our ancestors used to serve or to turn our trade as we wish? You are indeed mild-tempered and wise."
