Musannaf Ibn Abi Shayba 8:1702

Abu Bakr narrated to us, he said: Abu Khalid al-Ahmar narrated to us, from Ibn Jurayj, from Abdullah bin Uthman, from Sa’id bin Jubayr, that he stood with Ibn Abbas for the duration of a Surah from the Seven [long Surahs]. He said: I said, "Among the people are those who observe the recitation, and among them are those who hasten." He said: I said, "Like my recitation?" He said: I said, "You are light in recitation." He said: "Like my recitation."
