Hazrat Samurah bin Jundub (may Allah be pleased with him) used to say that the Prophet (peace and blessings of Allah be upon him) would observe silence twice during the prayer. Hazrat Imran bin Husain (may Allah be pleased with him) said that he did not remember this regarding the Prophet (peace and blessings of Allah be upon him). Both of them wrote a letter to Hazrat Ubayy bin Ka'b (may Allah be pleased with him) in this regard, in which they asked him about this issue. Hazrat Ubayy bin Ka'b (may Allah be pleased with him) replied in writing that Samurah had remembered correctly.
