Bukhari

Anas said: 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."

Narrated Abu Wa'il: A man came to Ibn Mas`ud and said, "I recited the Mufassal (Suras) at night in one rak`a." Ibn Mas`ud said, "This recitation is (too quick) like the recitation of poetry. I know the identical Suras which the Prophet used to recite in pairs." Ibn Mas`ud then mentioned 20 Mufassal Suras including two Suras from the family of (i.e. those verses which begin with) Ha, Meem [??] (which the Prophet used to recite) in each rak`a.

And reciting the last parts of a surah, and reciting surahs out of order, or reciting a surah before another surah that precedes it in the order of the Noble Qur’an, and reciting the beginning part of a surah—all of these are permissible. And it is narrated from Abdullah bin Sa’ib that the Prophet (peace and blessings of Allah be upon him) recited Surah Al-Mu’minun in the Fajr prayer. When he reached the mention of Musa (peace be upon him) and Harun (peace be upon him), or the mention of Isa (peace be upon him), he began to cough, so he bowed (for ruku’). And Umar (may Allah be pleased with him) recited one hundred and twenty verses of Surah Al-Baqarah in the first rak’ah, and in the second rak’ah he recited a surah from the Mathani (which contains about a hundred verses). And Ahnaf (may Allah be pleased with him) recited Surah Al-Kahf in the first rak’ah and Surah Yusuf or Surah Yunus in the second, and said that Umar (may Allah be pleased with him) had recited these two surahs in the Fajr prayer. Ibn Mas’ud (may Allah be pleased with him) recited forty verses of Surah Al-Anfal (in the first rak’ah) and in the second rak’ah he recited a surah from the Mufassal. And Qatadah (may Allah be pleased with him), regarding a person who divides a surah between two rak’ahs or repeats a surah in two rak’ahs, said: “All of it is from the Book of Allah.” (Therefore, there is no harm.)
