Allaah helped me to give up smoking and I started to fast from the 7th of Rajab until the end of Sha’baan. I did not separate Sha’baan and Ramadaan, because of the different fatwas concerning that. Please advise me, may Allaah reward you.
Praise be to Allaah Who has helped you to give up this haraam thing (smoking). We ask Allaah to make us and you steadfast in adhering to His religion until death.
Your joining Sha’baan and Ramadaan by fasting from one until the other is permissible.
