It is Wajib (incumbent) for every adult Muslim male 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 of the Takbeeraat of Tashreeq are as follows:
اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ لَا إلَهَ إلَّا اللَّهُ وَاَللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ وَلِلَّهِ الْحَمْدُ
Transliteration: 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.”
NB. Men should recite this Takbeer audibly whilst females should do so softly.
