"I said to my father: 'O my father! You offered Salat behind Allah's Messenger (S), Abu Bakr, Umar, Uthman, and Ali bin Abi Talib here in Al-Kufah for about five years. Did they say the Qunut?' He said: 'It is a newly invented matter my son.'"

I sneezed and said: Al-Hamdulillah, hamdan kathiran tayyiban mubarakan fih, mubarakan alaihi kama yuhibbu Rabbana Wa Yarda (All praise is due to Alah, many good blessed praises, blessings for Him as our Lord loves and is pleased with.) When Allah's Messenger (S) prayed and turned (after finishing) he said: 'Who was the speaker during the Salat?' No one spoke. Then he said it a second time: 'Who was the speaker during the Salat?' But no one spoke. Then he said it a third time: 'Who was the speaker during the Salat?'" So Rifa'ah bin Rafi bin Afra said: "It was I, O Messenger of Allah (S)." He said: "What did you say?" He said: "I said: 'Al-Hamdulillah, hamdan kathiran tayyiban mubarakan fih, mubarakan alaihi kama yuhibbu Rabbana Wa Yarda. The Prophet (S) said: "By the One in Whose Hand is my soul! I saw thirty-some angels competing over which of then would ascend with it."
