Time of Takbeer:
It is Sunnah to recite takbeer at any time during the first ten days of Dhu-l-Hijjah, however this Takbeer will specifically be recited after the Fajr prayer on the day of ‘Arafah (9th day of Dhu-l Hijjah), until after the ‘Asr prayer on the last day of at-Tashreeq (13th day of Dhu-l Hijjah)
Also called Takbeer al-Muqayyid one should make this Takbeer once after every obligatory (fard) Salaah. The Takbeeraat will be recited for 23 Salaahs in total.

Method of Reciting Takbeer:
A person will say the tasleem at the end of the obligatory prayer (fard salaah), he/she should pray for forgiveness (by saying Astaghfir-ullaah) three times, and say: “Allaahumma anta-s salaam wa minka-s salaam, tabaarakta yaa dha-l-jalaali wa-l-ikraam. (“O Allaah, You are al-Salaam [the One Who is free from all defects and deficiencies), and from You is all peace, blessed are You, O possessor of majesty and honour)”, then start the takbeer (mentioned below).

Takbeer Tashreek:
Recite: Allaahu akbar, Allaahu akbar, laa ilaaha ill-Allaah, Allaahu akbar, Allaahu akbar, wa Lillaahil-hamd (Allaah is Most Great, Allaah is Most Great, there is No god except Allaah, Allaah is Most Great, Allaah is Most Great, and all praise be to Allaah).
