Ali ibn Ibrahim from his father from Muhammad ibn Isa from Yunus from al-Ala ibn Razin from Muhammad: I asked Imam عليه السلام about a man who missed a rak‘ah with the imam (of prayer) from the prayer during the ‘Days of Tashriq’. (meaning 11th, 12th, and 13th of Dhul Hijjah) Imam عليه السلام said: “He completes the prayer and pronounces the takbir.”
