I hear some people reciting Takbir (saying: "Allahu Akbar [Allah is the Greatest]") after each Salah (Prayer) during the Days of Tashriq (11th, 12th and 13th of Dhul-Hijjah) until the ‘Asr (Afternoon) Prayer of the third day. Is this correct or not?
It is legislated to recite an unrestricted [in terms of time] or a restricted Takbir during ‘Eid-ul-Adha (the Festival of the Sacrifice). The unrestricted Takbir can be recited at any time from the beginning of Dhul-Hijjah until the last Day of Tashriq. The restricted Takbir should be recited after the Obligatory Daily Salahs, starting from the Fajr (Dawn) Prayer of the Day of
`Arafah until the ‘Asr Prayer on the last Day of Tashriq. The evidence for the permissibility of doing this is the Ijma‘ (consensus of scholars) and the practice of the Sahabah (Companions of the Prophet, may Allah be pleased with them).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
