Praising Allah as He deserves to be praised is one of the noblest acts of worship by means of which a person may draw closer to Allah (may He be glorified and exalted), and attain great reward in this world and the hereafter. In this hadith, Rifa‘ah ibn Rafi‘ (may Allah be pleased with him) narrates that he was praying with the Prophet (blessings and peace of Allah be upon him) one day, and the Prophet (blessings and peace of Allah be upon him) said after rising from bowing: “Sami‘a Allahu limanhamidah(Allah hears those who praise Him).” A man who was praying behind the Prophet (blessings and peace of Allah be upon him) said: Rabbanawalaka al-hamduhamdankathirantayyibanmubarakanfihi (Our Lord, to You be praise, much good and blessed praise). What is meant is: praise that is free of showing off and seeking reputation, in which there is much good. The one who said that was Rifa‘ah ibn Rafi‘ (may Allah be pleased with him), the narrator of the hadith, as is stated in the report narrated by Abu Dawud. After finishing the prayer, the Prophet (blessings and peace of Allah be upon him) asked who had said those words, and Rifa‘ah (may Allah be pleased with him) said to him: I was the one who said that, O Messenger of Allah. So the Prophet (blessings and peace of Allah be upon him) told him that he had seen a number of angels – as many as thirty-odd – rushing , each of them wanting to write down these words before the others. The word translated here as “-odd” refers to a number between three and nine. This hadith highlights the virtue of praising and remembering Allah (may He be glorified). It indicates that it is prescribed for the one who is praying behind an imam to say some of the dhikr out loud, so long as that will not disturb the people with him..
