Joining Sha’baan to Ramadaan
Question

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 Allah.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. 
You have followed the Sunnah by doing that. See question no. 13726 and 26850.
