O ye who believe! Follow not the footsteps of the devil. Unto whomsoever followeth the footsteps of the devil, lo! he commandeth filthiness and wrong. Had it not been for the grace of Allah and His mercy unto you, not one of you would ever have grown pure. But Allah causeth whom He will to grow. And Allah is Hearer, Knower.
[Surah An-Nur : 21]

Abu Hurairah (r.a.) said: The Messenger of Allah (saws) said, "Verily, Allah likes three things for you and disapproves three things. He likes that you should worship Him Alone, not to associate anything with Him (in worship) and to hold fast to the Rope of Allah and not to be divided among yourselves; and He disapproves for you irrelevant talk, persistent questioning and the squandering of the wealth."

[Sahih Muslim]
