Rifa bin Rafi reported, "I prayed behind the Messenger of Allah ﷺ and I sneezed, so I said, 'Praise be to Allah, abundant, wholesome, and blessed praise, blessed upon Him, as our Lord loves and is pleased with.'When the Messenger of Allah ﷺ finished the prayer and turned around, he asked, 'Who was the one speaking during the prayer?'No one spoke.He asked a second time, 'Who was the one speaking during the prayer?'No one spoke.He asked a third time, 'Who was the one speaking during the prayer?'Rifa bin Rafi bin Afra said, 'It was I, Messenger of Allah.'He asked, 'What did you say?'I replied, 'I said, Praise be to Allah, abundant, wholesome, and blessed praise, blessed upon Him, as our Lord loves and is pleased with.'The Prophet ﷺ said, 'By the One in whose hand is my soul, thirty-some angels rushed to see which of them would ascend with it.'"
حدثنا قتيبة حدثنا رفاعة بن يحيى بن عبد الله بن رفاعة بن رافع الزرقي عن عم أبيه
صليت خلف رسول الله ﷺ فعطست فقلت الحمد لله حمدا كثيرا طيبا مباركا فيه مباركا عليه كما يحب ربنا ويرضى فلما صلى رسول الله ﷺ انصرف فقال من المتكلم في الصلاة فلم يتكلم أحد ثم قالها الثانية من المتكلم في الصلاة فلم يتكلم أحد ثم قالها الثالثة من المتكلم في الصلاة فقال رفاعة بن رافع ابن عفراء أنا يا رسول الله قال كيف قلت قال قلت الحمد لله حمدا كثيرا طيبا مباركا فيه مباركا عليه كما يحب ربنا ويرضى فقال النبي ﷺ والذي نفسي بيده لقد ابتدرها بضعة وثلاثون ملكا أيهم يصعد بها
[Its isnad is hasan]. Abu Dawud also narrated it in the Book of Prayer, chapter on what one opens the prayer with of supplication, hadith 773, and Nasai, 2/145, hadith 932, from Qutayba, with the same wording. It also has another route in Bukhari, hadith 799.There are also narrations on this subject from Anas [Muslim, hadith 537], Waail bin Hajar [Nasai, hadith 933], and Amir bin Rabia [Abu Dawud, hadith 774].
