Assalamu-alaikum,
Insha Allah, you may find the following of use:
1. Seek refuge from shayataan: “A’oozu billahi minash shaytaanir rajeem.” - repeat this frequently.
“And if an evil whisper comes to you from Shaytaan then seek refuge with Allah. Verily, He is All-Hearer, All Knower.”
(Surah Al-A’raf 7 : 200)
2.Immediately move away from the place/ people enticing you towards sin.
3. Remembering that Allah (subhanawataála) is watching, and imagining how DISPLEASED your RABB would be - the very one who is in control of every beat of your heart, to whom you owe your very existence.
Imagine how much sorrow and regret you will feel afterwards.
Imagine Allah Taa'la as your most beloved.
Can you imagine breaking the heart of your beloved?
So too, imagining how Allah (subhanawatála) - my MOST BELOVED of ALL - would feel watching my disobedience.
As soon as you find yourself even moving towards a sin - saying to yourself: 'My Allah is watching me. My Allah is watching me.
I cannot go against the One to whom I owe my Life.'
4. Remembering death immediately.
Imagining that Allah Taa'la can take your life away - right at that moment, whilst you may be engaged in an evil deed.
And that you would be brought back on the day of Qiyamat - in the exact manner of your death.
5. Imagining that IF death were to find you now, how embarrassed and ashamed your family would be to find you in such a situation.
No matter how much good you may have done during your life, this is all that will linger in the memories of your loved ones.
6. Remembering the ayats from the Quraan that mention the reward of Jannah, in return for your obedience to Allah:
“BUT AS FOR HIM WHO FEARED (IN THIS WORLD) TO STAND BEFORE HIS LORD (IN THE HEREAFTER) AND RESTRAINED HIMSELF FROM (UNLAWFUL INDULGENCE IN) LUST, LO! JANNAT WILL BE HIS HOME.”
[SURAH AN-NAAZI’AAT 79 : 40/41]
And remembering that no matter how tempting something may be appearing at this point in time.......nothing in this dunya is worth losing the pleasure of Jannah, and enduring the punishment of Jahannum.
7. And finally, when you have been able to fight/ ward off the temptation to sin - imagining how pleased your Creator is with you.
How beloved you are to Him.
And experience the sweetness of this type of imaan - of the one that trys to resist, purely for the pleasure of Allah, as well as the sweetness of being stronger than Shaytaan.
EDIT:
8. Also: remembering that: '.....Allah will not change a condition of a people until they change what is in themselves' (13:11).
Which means that if we are expecting our lives to improve - then this would not be possible, until we submit in obedience to Allah, and fight our own desires.
If we cannot be bothered by the commands of our Rabb, then why would He be concerned in changing our condition?
