It is necessary (wajib) for every Muslim (male or female, whether praying in congregation or alone) to make the following takbir (declaration of the greatness of Allah) immediately after each obligatory (fard) prayer. Time: From: the Fajr Prayer on the 9th of Dhu’l Hijjah (the Day of `Arafah) To: the Asr Prayer on the 13th of Dhu’l Hijjah. Thus, these takbirs last 5 days, and 23 prayers.
