It is reported that Al-Aswad [b. Yazîd Al-Nakha’î] used to complete the recitation of the Quran in Ramadan every two nights; sleeping between al-maghrib and al-‘ishâ. Outside of Ramadân, he used to complete a recitation every six nights.
Abû Nu’aym, Hilyatu Al-Awliyâ` 1:250.
It is related from Al-Rabî’ b. Sulaymân, “Muhammad b. Idrîs Al-Shâfi’î used to complete reciting the Quran in the month of Ramadan sixty times, all in the prayer.”
It is reported that Abul-Ash-hab said, “Abû Al-Rajâ` [Al-Atârudî] would complete with us a recitation of the Quran in the night prayers of Ramadan every ten days.”
It is reported that Qatâdah used to complete a recitation of the Quran once every seven nights, and when Ramadan came, once every three nights. During the last ten nights, he would complete a recitation every night.
It is reported that Al-Bukhârî used to complete a recitation [of the Quran] once a day in Ramadan, and would pray after Tarâwîh every night, completing another recitation every three nights.
Al-Dhahabî, Siyar A’lâm Al-Nubalâ` 12:439
After mentioning some similar examples from the Salaf, Ibn Rajab says in Latâ`if Al-Ma’ârif p319:
The prohibition of reciting the Quran in less than three days [found in some ahadith] refers to doing so regularly [throughout the year]. As for virtuous times, like Ramadan – especially the nights in which it is hoped Laylatu Al-Qadr will occur – or virtuous places, like Makkah – for those who enter it and are not residents there, then it is recommended to increase in reciting the Quran, making the most of the time and the place. This is the position of [Imam] Ahmad, Ishâq [ibn Râhûyah] and other Imams, and the practice of others [from the Salaf] indicates [they held the same position].
