It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) would stand for prayer at night and begin his prayer, he would say Allahu Akbar and recite this supplication: Subhanaka Allahumma wa bihamdika tabaarakasmuka wa ta'ala jadduka wa la ilaha ghayruk. Then he would say La ilaha illallah three times, then recite: A'udhu billahi as-sami'il 'aleem min ash-shaytanir-rajim min hamzihi wa nafkhihi. Then he would say Allahu Akbar three times and then recite: A'udhu billahi as-sami'il 'aleem min ash-shaytanir-rajim min hamzihi wa nafkhihi wa nafathihi.

Translation of the supplications: O Allah! You are pure and with Your praise, blessed is Your name, exalted is Your majesty, and there is no deity except You. There is no true deity except Allah. I seek refuge with Allah, the All-Hearing, the All-Knowing, from the accursed Satan and from his madness and arrogance. Allah is the Greatest. I seek refuge with Allah, the All-Hearing, the All-Knowing, from the accursed Satan and from his madness, his arrogance, and his poetry.

It is narrated from Sayyiduna Abu Umamah Bahili, may Allah be pleased with him, that when the Noble Prophet, peace and blessings be upon him, would stand for prayer at night and enter into prayer, he would say Allahu Akbar three times, La ilaha illallah three times, and Subhan Allah wa bihamdihi three times, then he would recite: A‘udhu billahi min ash-shaytan ir-rajim min hamzihi wa nafkhihi wa nafthihi.

Sayyiduna Jubair bin Mut’im says: I heard that the Noble Prophet (peace and blessings be upon him) recited three times in a voluntary prayer: ALLAHU AKBAR KABE AN, three times ALHAMDULILLAHI KATHE AN, and three times SUBHANALLAHI BUKRATAN WA ASEELA, and then said: A’UDHU BILLAAHIS SAMEE’IL ‘ALEEMI MINA AYTAANIR RAJEEMI MIN HAMZIH WA NAFTHIH WA NAFKH. I asked: O Messenger of Allah! What is meant by his hamz, nafth, and nafkh? He (peace and blessings be upon him) replied: Hamz means madness and insanity, which befalls the son of Adam, and then he described the state of that madness, in which he falls unconscious. Nafkh means arrogance, and nafth means poetry.

Sayyiduna Abdullah bin Umar (may Allah be pleased with him) says that once we were performing prayer with the Messenger of Allah (peace and blessings be upon him), when suddenly a man said these words: "Allah is the Greatest, very great. All praise is for Him, which is very much. He is pure; morning and evening we declare His purity." The Messenger of Allah (peace and blessings be upon him) asked: Who was the one who said these words? A man replied: O Messenger of Allah! It was I. The Prophet (peace and blessings be upon him) said: I was amazed at these words, for the gates of the heavens have been opened for them. Ibn Umar (may Allah be pleased with him) says: Since I heard the Messenger of Allah (peace and blessings be upon him) say this, I have never abandoned these words.

It is narrated from Sayyiduna Abdullah bin Amr bin Aas (may Allah be pleased with him) that a man once entered the prayer and he said these words: "Alhamdulillah mil'a as-samawat" and further glorified Allah and made supplication. The Messenger of Allah (peace and blessings be upon him) said: Who was the person who recited these words? He said: It was I. The Prophet (peace and blessings be upon him) said: Certainly, I saw the angels passing these words to one another.

Sayyiduna Abdullah bin Abi Awfa (may Allah be pleased with him) says that we were standing in a row following the Messenger of Allah (peace and blessings be upon him) when a man came and said: Allahu Akbar Kabiran wa Subhanallahi Bukratan wa Aseela. (Allah is the Greatest, very great. He is pure, morning and evening we declare His purity.) The Muslims raised their heads (towards him) and considered it bad and said: Who is it that is raising his voice above the voice of the Messenger of Allah (peace and blessings be upon him)? But when the Messenger of Allah (peace and blessings be upon him) finished, he asked: Who was the one raising his voice? It was replied: O Messenger of Allah! It is he. Then the Prophet (peace and blessings be upon him) said: By Allah, I saw your words ascending to the sky until a door was opened for them and they entered it.

It is narrated from Sayyiduna Wa’il bin Hujr (may Allah be pleased with him), he says: I prayed with the Noble Prophet (peace and blessings be upon him), and a man said: "Alhamdulillahi kathīran ṭayyiban mubārakan fīh." (All praise is due to Allah, abundant, pure, and blessed praise.) When the Messenger of Allah (peace and blessings be upon him) finished the prayer, he asked: Who is the one who said these words? That man said: O Messenger of Allah! It was me, and my intention was only good. The Prophet (peace and blessings be upon him) said: Surely, for these words, the gates of the heavens have been opened, and nothing stopped them before reaching the Throne.
