QUESTION:

When does the takbeer of Zul Hijjah start and when does it end?

ANSWER:

In the name of Allah, Most Compassionate, Most Merciful,

The takbīr al-tashrīq is to be recited after every fardh ṣalāh starting from the fajr of the 9th of Dhul Hijah until after the ‘aṣr of the 13th of Dhul Hijjah. 

And Allah, the Almighty, knows best,
