Hadith: Those who used to recite the Qur’an to us from the Prophet's Companions related to us

عن أبي عبد الرحمن السُّلمي قال: حدثنا مَن كان يُقرئنا من أصحاب النبي صلى الله عليه وسلم أنهم كانوا يقترئون من رسول الله صلى الله عليه وسلم عشر آيات، فلا يأخذون في العشر الأخرى حتى يعلموا ما في هذه من العلم والعمل، قالوا: فعلمنا العلم والعمل.
[حسن] - [رواه أحمد]

‘Abdur-Rahmān as-Sulami reported: Those who used to recite the Qur’an to us from the Prophet's Companions related to us that they would listen to ten verses from the Prophet (may Allah’s peace and blessings be upon him) and not move to the next ten verses until they learned the knowledge and application contained therein. They said: So, we learned knowledge and application.
Hasan/Sound. - [Ahmad]

Explanation

The Companions (may Allah be pleased with them) used to recite ten verses of the Qur’an, after hearing them from the Prophet (may Allah’s peace and blessings be upon him), and would not move to other verses until they learned the knowledge and action contained in the first ten verses. Knowledge refers to the theoretical and creedal issues and so on; whereas action refers to the practical application of worship, dealings, and the like. Thus, they used to learn and act upon what they learned right away - without delay.
