A man from the Ansar used to lead the people in prayer at the mosque of Quba. Whenever he began a surah to recite for them in the prayer, he would start with "Say, He is Allah, the One" [Ikhlas 112:1] until he finished it, then he would recite another surah along with it, and he did this in every rakah.His companions spoke to him about it, saying, "You recite this surah, then you do not consider it sufficient until you recite another surah with it. Either recite it alone, or leave it and recite another surah."He replied, "I will not abandon it. If you want me to lead you in prayer with it, I will do so, and if you dislike it, I will leave you."They considered him the best among them and disliked the idea of anyone else leading them in prayer. So when the Prophet ﷺ came to them, they informed him of the matter.The Prophet ﷺ said, "So-and-so, what prevents you from doing what your companions are asking, and what makes you recite this surah in every rakah?"He answered, "Messenger of Allah, I love it."The Messenger of Allah ﷺ said, "Your love for it has admitted you to Paradise."
كان رجل من الأنصار يؤمهم مسجد قباء. فكان كلما افتتح سورة يقرأ لهم في الصلاة فقرأ بها، افتتح ب {قل هو الله أحد} حتى يفرغ منها، ثم يقرأ بسورة أخرى معها، وكان يصنع ذلك في كل ركعة. فكلمه أصحابه فقالوا: إنك تقرأ بهذه السورة، ثم لا ترى أنها تجزيك حتى تقرأ بسورة أخرى، فإما أن تقرأبها، وإما أن تدعها وتقرأ بسورة أخرى، قال: ما أنا بتاركها، إن أحببتم أن أؤمكم بها فعلت وإن كرهتم تركتكم. وكانوا يرونه أفضلهم، وكرهوا أن يؤمهم غيره، فلما أتاهم النبي ﷺ أخبروه الخبر. فقال: يا فلان ما يمنعك مما يأمر به أصحابك، وما يحملك أن تقرأ هذه السورة في كل ركعة؟ فقال: يا رسول الله! إني أحبها، فقال رسول الله ﷺ: إن حبها أدخلك الجنة.
Tirmidhi (2901) narrated it, saying, Muhammad bin Ismail (Bukhari) narrated to us, Ismail bin Abu Uways narrated to us, Abdul-Aziz bin Muhammad narrated to us, from Ubaydullah bin Umar, from Thabit Bunani, from Anas bin Malik, and he related the hadith.Tirmidhi said, "It is hasan gharib sahih from this route, from the hadith of Ubaydullah bin Umar, from Thabit. Mubarak bin Fadala narrated from Thabit, from Anas, that a man said, 'Messenger of Allah, I love this surah, "Say, He is Allah, the One".' The Prophet said, 'Your love for it will admit you into Paradise.'" He said, Abu Dawud Sulayman bin Ashath narrated this to us, Abu Walid narrated to us, Mubarak bin Fadala narrated to us with this. End of quote.I say, from this route it was also narrated by Ahmad (12512), Ibn Hibban (792), and Darimi (3478), and Bukhari mentioned it in the Book of Adhan (774) as a suspended narration (muallaq), from Ubaydullah bin Umar, from Thabit, from Anas. I say, this is the narration that Tirmidhi connected from Bukhari, from Ismail bin Abu Uways, as mentioned previously.
