Is it valid to pray a prayer with different prescribed actions behind one performing a differing ritual prayer, such as eclipse prayer or Friday prayer?
Chapter on Imamate and Congregational Prayer

Book of Prayer
Primary text
If one of the two prayers differs from the other in its actions, such as the eclipse prayer behind one performing a different prayer, or any other prayer behind one performing the Friday prayer or the eclipse prayer, the prayer is invalid based on a single narration. This is because it leads to a forbidden divergence in actions from the Imam.
