To do nasihah to Allah one should have the right or correct intention in one’s heart to fulfill the rights of Allah, even when one is excused and it is beyond one’s capacity to perform these obligations.
Sometimes a person may not be able to carry out an obligation but at least he has good intentions in his heart to fulfill it in the first place.
The actions of the heart (i.e. to have hope in Allah’s mercy, to trust Him, to fear Him and to seek refuge in Him), and the actions of the limbs (prayers, Zakah, etc.) also fall under or belong to nasihah to Allah.
Honesty is also another part of this great concept. In whatever we do we should always be honest with Allah, invariably with ikhlas (sincerity). In fact ikhlas should be the first thing that a Muslim should achieve when we talk about nasihah to Allah.
Nasihah to His Book , the Glorious Qur’an
This includes:-
Believing that the Qur’an is from the Almighty Allah, that it is the Word of Allah and that it is not like the word of man.
According to one’s ability, to read and recite the Qur’an and to practice that which it teaches.
To study it’s admonitions, lessons and parables.
Calling of others to believe in the Qur’an.
To defend and protect it from any kind of distortion or misinterpretation.
Defending the Qur’an against the false claims made against it.
Having proper respect for the Qur’an and treating the Qur’an in a proper manner – e.g. to be careful not to throw away a piece of paper which has an ayat of the Qur’an printed on it (magazine article, etc.) as it may be stepped on – we should also be cognizant if we see such a piece of paper on the ground to pick it up and keep it away safely or destroy it by burning it so that it is not subject to disrespect.
