It was narrated that Shaqeeq bin Salamah said:

A man from Banu Bajeelah who was called Naheek bin Sinan came to ‘Abdullah (رضي الله عنه) and said: O Abu ‘Abdur-Rahman, how do you recite this verse? Do you find it ya' or alif? (i.e., ghair asin or ghair yasin) "water the taste and smell of which are not changed (min ma’in ghair asin)” (Muhammad 47:15). ‘Abdullah said to him: Have you read all the Qur'an except this? He said: I recite al-Mufassal (the Soorahs from Qaf to the end of the Qur'an) in one ruk'ah. ‘Abdullah said: Do you recite Qur'an as you recite poetry? The best part of the prayer is bowing and prostration, and some people recite the Qur'an but it does not go past their collarbones. But if he recites it and it takes root in his heart, he will benefit from it. I know the pairs of soorahs that the Messenger of Allah (ﷺ) used to recite in one rak'ah. Then he went in and asked him, then he came out to us and said: Twenty soorahs from the beginning of al-Mufassal, in the Mushaf of 'Abdullah.
