The words of Takbir at-Tashriq are:
الله أكبر الله أكبر لا إله إلا الله والله أكبر الله أكبر ولله الحمد
Transliteration: Allahu Akbar Allahu Akbar Laa Ilaaha illallaahu wa Allahu Akbar Allahu Akbar wa lillahi al-hamd
Translation: Allah is the Greatest. Allah is the Greatest. There is no deity worthy of worship but Him. Allah is the Greatest. Allah is the Greatest. And for Allah is all praises.
It is Wajib (compulsory) to read the Takbir at-Tashriq once audibly immediately after every congregational and non-congregational Fardh Salah and Jumu`ah Salah, whether a traveler or non-traveler, a male or female, from the Fajr prayer of the day of Arafat (9th Thul Hajj) to Asr of the fifth day (13th Thul Hajj).
