Regarding the Ayam-al-Beed fasts of DhulHijjah, would one be able to fast on the 13th as that is also one of the days of Tashriq?
Regarding your question; “It is Makruh Tahrimi (prohibitively disliked) to fast on the two Eid’s and on what is known as the Ayam-al-Tashriq which are the 11th, 12th and 13th of the Islamic month of DhulHijjah. (Fatawa al-Hindiyah 1:201, Dar ihya al-Turath al-Arabi).
Only Allah knows best.
