It is Wajib (incumbent) for every adult muslim to recite the Takbeeraat of Tashreeq after every Fardh Salaat-performed with Jamaat or individually from the Fajr of the 9th of Zul-Hijjah to the Asr of the 13th of Zul Hijjah. The Takbeeraat should be recited once only. The words are as follows:
Allahu Akbar, Allahu Akbar laa ilaha illallahu wallahu akbar. Allahu Akbar walillaahil hamd.
Translation: “Allah is the Greatest, Allah is the Greatest. There is no deity besides Allah and Allah is the Greatest. Allah is the Greatest and all praises belong to Him Alone.”
