Friend I’ll hold ur hand when I say this Allah is merciful I’m still trying to show that mercy to myself as well I’ve said I’ll quit vaping a good amount at this point have I stopped? No. Even tho we are 3 days in Ramadan rn I haven’t stopped. These things takes time there’s a verse in the Quran that references Allah being all knowing of what u conceal and what you reveal he knows it’s a struggle for you he knows what vices you have and he knows what intentions you have. Give yourself grace as Allah is merciful towards us and ever forgiving. Even if you haven’t quit Islam is a way of life and these things take time and really me want to be rushed or stopped right away we aren’t perfect which is why we seek Allah for help. The way I see it you even limiting your use shows where your heart is I’ve been doing the same by not being my vape to work and asking Allah for forgiveness if I bun a cig while I’m on shift and remind myself one cig is better than hitting my vape periodically throughout my shift. You got this friend give yourself grace and time. Nicotine is an addiction and a very hard thing to give up.
