In the battle between reason/religion and whims/desires, we have the following weapons at our disposal:
1. We should remember the glory and greatness of Allah, and feel that He is too great to be sinned against as He is all-seeing and all-hearing. Whoever thinks of the greatness of Allah will never be at ease in committing wrong actions.
2. If we claim to love Allah, then we should not disobey Him, because of that love. A person should be obedient to the One he claims to love. Those who refrain from committing wrong action out of their love for Allah are of the highest status in His sight, as are those who worship Him out of love for Him. There is a great difference between the one who obeys Allah and abstains from wrong action Out of love, and the one who does so out of fear of punishment.
3.

Allaah - the Most High - said: "O you who believe! Remember Allaah and remember Him a lot." [33:4I].

"Those men and women who remember Allaah a lot." [33:35].

"So when you have finished the rights of your Pilgrimage, then remember Allaah as you remember your fore-father, or with more intense remembrance." [2:200].

These verses contain a command to remember Allaah intensely and abundantly, since the worshipper is in dire need of [remembering Allaah] and cannot do without it even for a twinkling of an eye. This is because every moment that a person does not spend in the dhikr (remembrance) of Allaah will not be of any benefit to him. Rather, the harm entailed in being neglectful of the dhikr of Allaah is far greater than any benefits that can be gained.
