Mishkat al-Masabih 766

Samura b. Jundub said that he remembered from God's Messenger two periods of silence, one when he said the takbir, and one when he finished reciting, “Not of those with whom Thou art angry, nor of those who go astray,”* and Ubayy b, Ka‘b corroborated him. *Al-Qur’an, 1:7 Abu Dawud transmitted it, and Tirmidhi, Ibn Majah and Darimi transmitted something similar.
