Why we are created
And I (Allâh) created not the jinns and humans except they should worship Me (Alone).
Knowledge and Actions key to success
So know (O Muhammad SAW) that Lâ ilâha ill-Allâh (none has the right to be worshipped but Allâh), and ask forgiveness for your sin, and also for (the sin of) believing men and believing women. And Allâh knows well your moving about, and your place of rest (in your homes).
Condition of Mankind in general and condition of Muslims in particular will not change unless
Verily! Allâh will not change the good condition of a people as long as they do not change their state of goodness themselves (by committing sins and by being ungrateful and disobedient to Allâh) (Ra'd 13:11)
Position of those with pure, clean hearts on the Day of Judgement
The Day whereon neither wealth nor sons will avail, except him who brings to Allâh a clean heart [clean from Shirk (polytheism) and Nifâq (hypocrisy)].
The ultimate result of correct Belief and Righteous actions
Certainly! Allâh will admit those who believe (in the Oneness of Allâh Islâmic Monotheism) and do righteous good deeds, to Gardens under which rivers flow (Paradise), while those who disbelieve enjoy themselves and eat as cattle eat, and the Fire will be their abode. (Muhammad 47:12)
