I think that the month of Ramadaan is an opportunity for the one who is sincerely resolved and wants to give up this foul, harmful habit of smoking. I think that it is an opportunity because he is going to abstain from it throughout the day in Ramadaan, and at night he can distract himself from it by means of the food and drink that Allaah has permitted to him, and by frequenting the mosques and attending gatherings of righteous people, and he can keep away from those who have this habit. If he abstains from it throughout the month, then that will be a great help to him in giving it up for the rest of his life. This is an opportunity which smokers should not miss. I personally quit 10 years smoking habit during Ramadaan.
