It is for the sake of accomplishing Tawheed that the messengers were sent and the Divine Books were revealed. And by accomplishing the phrase of sincerity we will be able to formulate a strong nation that has its leadership and its immunity, by the permission of Allah (e.g; a nation that will command the good and forbid the evil and believe in Allah Alone).

"Verily, Allah will help those who help His (Cause), Truly, Allah is All-Strong, All Mighty".

And with Allah rests the end of (all) matters" (of creatures).

But as soon as they have studied them and understand them they crave after them, love them and seek more from the.
