Alif, Lam, Mim.
Do men think that they will be left alone on saying, "We believe", and that they will not be tested?
We did test those before them, and Allah will certainly know those who are true from those who are false.
Do those who practise evil think that they will get the better of Us? Evil is their judgment!
For those whose hopes are in the meeting with Allah (in the Hereafter, let them strive); for the term (appointed) by Allah is surely coming and He hears and knows (all things).
And if any strive (with might and main), they do so for their own souls: for Allah is free of all needs from all creation.
Those who believe and work righteous deeds,- from them shall We blot out all evil (that may be) in them, and We shall reward them according to the best of their deeds.(Al-Ankaboot :1-7 )
