May the peace, blessings and mercy of God be upon you all.
I am aware that Sunnis believe that the Messenger of God used to fast on Mondays and Thursdays. What do the Shias believe with this matter? Is it true, or not? Do Shias condemn this statement or not? Do Shias have a different belief?
Also, I would like to fast outside of Ramadan because it increases my taqwa, am I allowed to do this, if no, why? If yes, on what days? [Any hadith on fasting outside of Ramadan for Shias?]
I would like to say that I am not here to refute with anyone.
Thank you.
