"The first people to declare their Islam publicly were seven: The Messenger of Allah, Abu Bakr, 'Ammar and his mother Sumayyah, Suhaib, Bilal and Miqdad. With regard to the Messenger of Allah, Allah protected him through his paternal uncle Abu Talib. With regard to Abu Bakr, Allah protected him through his people. As for the rest, the idolators seized them and made them wear coats of chain-mail and exposed them to the intense heat of the sun. There was none of them who did not do what they wanted them to do, except for Bilal. He did not care what happened to him for the sake of Allah, and his people did not care what happened to him. Then they gave him to the children who took him around in the streets of Makkah while he was saying, 'Ahad, Ahad (One, One).'"

Mihjan bin Al-Adra' narrated to him that the Messenger of Allah (SAW) entered the masjid and there was a man who had finished his prayer and he was reciting the tashahhud. He said: "Allahumma inni as'aluka ya Allah! Bi-annakal-Wahidul-Ahad us-Samad, alladhi lam yalid wa lam yowled, wa lam yakun lahu kufuwan ahad, an taghfirali dhunubi, innaka antal-Ghafurur-Rahim (O Allah, I ask of You, O Allah, as You are the One, the Only, the Self-Sufficient Master, Who begets not nor was He begotten, and there is None equal or comparable to Him, forgive me my sins, for You are the Oft-Forgiving, Most Merciful.)" The Messenger of Allah (SAW) said: "He has been forgiven," three times.

"I went out with the Messenger of Allah and heard a man reciting Qul Huwa Allahu Ahad [Sūrah Al-Ikhlāṣ] so the Messenger of Allah (ﷺ) said: 'It is obligatory.' I said: 'What is obligatory?' He said: 'Paradise (is obligatory as a reward for the man).'" Reference: Jami` at-Tirmidhi 2897.

"The Prophet (saas) heard a man say: 'Allahumma! Inni as'aluka bi-annaka Antallahul-Ahadus-Samad, alladhi lam yalid wa lam yuwlud, wa lam yakun lahu kufuwan ahad (O Allah! I ask You by virtue of Your being Allah, the One, the Self-Sufficient Master, Who begets not nor was begotten, and there is none co-equal or comparable to Him).' The Messenger of Allah (saas) said: 'He has asked Allah by His Greatest Name, which if He is asked thereby He gives, and if He is called upon thereby He answers.'"

that the Messenger of Allah (SAW) said: "Gather and I shall recite to you one third of the Qur'an." He said: "So whoever was to gather did so, then the Messenger of Allah (SAW) came out and recited Qul Huwa Allahu Ahad. Then he went back in. Some of them said to each other: "The Messenger of Allah (SAW) said: 'I shall recite to you one third of the Qur'an' I thought that this was news from the Heavens." Allah's Prophet (SAW) came out and said: "Indeed I said that I would recite to you one third of the Qur'an, and it is indeed equal to one third of the Qur'an."

"When Allah’s Messenger (Allah bless him and give him peace) went to his mattress each night, he joined the palms of his hands, then breathed into them and recited into them: “Say: ‘He is Allah, One [qul Huwa'llahu Ahad]!' (Al-Qur'an;112:1), and: “Say: ‘I take refuge with the Lord of the Daybreak [qul a'udhu bi-Rabbil-falaq]!' (Al-Qur'an;113:1), and: “Say: ‘I take refuge with the Lord of humankind [qul a'udhu bi-Rabbi’n-nas]!' (Al-Qur'an;114:1), Then he passed them over as much of his body as he could, beginning with his head and his face and the front of his body, doing that three times.”

that the Messenger of Allah (SAW) said to a man among his Companions: "Have you married O so-and-so?" He said: "No by Allah O Messenger of Allah! And I do not have anything to marry with."

He said: "It is a fourth of the Qur'an." He said: "Do you not know Qul Ya Ayyuhal-Kafirun?" He said: "Of course." He said: "It is a fourth of the Qur'an."

One of the Ansar used to lead the Ansar in Salat in the Quba' mosque and it was his habit to recite Qul Huwal-lahu Ahad whenever he wanted to recite something in Salat. When he finished that Surah, he would recite another one with it. He followed the same procedure in each Rak'a. His companions discussed this with him and said, "You recite this Surah and do not consider it sufficient and then you recite another. So would you recite it alone or leave it and recite some other." He said, "I will never leave it and if you want me to be your Imam on this condition then it is all right ; otherwise I will leave you." They knew that he was the best amongst them and they did not like someone else to lead them in Salat. When the Prophet (saws) went to them as usual, they informed him about it. The Prophet (saws) addressed him and said, "O so-and-so, what forbids you from doing what your companions ask you to do ? Why do you read this Surah particularly in every Rak'a ?" He repiled, "I love this Surah." The Prophet (saws) said, "Your love for this Surah will make you enter Paradise."

"There was a man from the Ansar who led them (in Salat) at Masjid Quba. Every time he was to recite a Surah for them during Salat, he would begin by reciting Qul Huwa Allahu Ahad until he finished, then he would recite another Surah with it. He did that in each Rak'ah. His companions talked to him and said: 'You recite this Surah. You should either recite it or leave it and recite another Surah.'" He said: "I shall not leave it, if you would like me to lead you with it then I shall do so, and if you do not like it then I shall leave you." And they considered him the best among them, and they did not like the idea of someone else leading them. So when the Prophet (SAW) came to them they informed him about what had happened and he (SAW) said: "O so-and-so! What prevents you from doing what your companions told you to do, why do recite this Surah in every Rak'ah" He said: "O Messenger of Allah! Indeed I love it." So the Messenger of Allah (SAW) said: "Your love for it shall have you admitted into Paradise."

the Messenger of Allah (saas) said: "Allah has ninety-nine names, one hundred less one, for He is One and loves the odd (numbered). Whoever learns them will enter Paradise.
