Is the Dhuhr prayer valid behind an Imam praying 'Asr?
Chapter on Imamate and Congregational Prayer

Book of Prayer
Primary text
There are two narrations concerning praying Dhuhr behind one praying 'Asr. Isma'il ibn Sa'id narrated the permissibility, while others narrated the prohibition. Isma'il ibn Sa'id narrated that Ahmad permitted praying a required prayer behind an Imam praying Taraweeh in Ramadan. However, in another narration, Ahmad disliked that one should follow the Taraweeh prayer for the 'Isha' prayer.

This issue is a branch of the permissibility of a mandatory worshipper following a voluntary worshipper, which has already been discussed.
