Sayyiduna Sa'id bin al-Mundhir al-Ansari (may Allah be pleased with him) narrates that he said: "O Messenger of Allah! Should I recite the Qur'an in three days?" The Prophet (peace and blessings be upon him) said: "Yes." The narrator says: So he continued reciting the Qur'an in this way until he passed away.
Ahmad and al-Tabarani in al-Mu'jam al-Kabir recorded it, except that he narrated these words: He (peace and blessings be upon him) said: "Yes, if you are able to." Its chain contains Ibn Lahi'ah, and there is criticism concerning him.
