Musannaf Ibn Abi Shaybah

Hazrat Abdullah bin Uthman narrates that Hazrat Saeed bin Jubair stayed with Hazrat Ibn Abbas (may Allah be pleased with them both) (at the Jamarat) for the duration it takes to recite seven surahs. The narrator says, I asked, "Some people recite quickly and some recite slowly?" He replied, "It should be like my recitation." I said, "But you recite very slowly." He said, "(Yes,) it should be like my recitation."
