As-Sa’ib b. Yazid said

'Umar ordered Ubayy b. Ka'b and Tamim ad-Dari to lead the people in eleven rak'as during the night in Ramadan. The reader was reciting [a sura with over] a hundred verses in each rak'a so that we leaned on our sticks because of standing so long, and we did not depart till the dawn was beginning to break. Malik transmitted it.
