Nafi reported,

Ibn Umar used to perform his voluntary prayers in the same spot where he had prayed the obligatory prayer, and Qasim did the same. It is reported from Abu Hurairah, traced back to the Prophet ﷺ, that the imam should not perform voluntary prayers in the spot where he led the obligatory prayer, but this report is not authentic.

وقال لنا آدم حدثنا شعبة، عن أيوب،

عن نافع، قال

كان ابن عمر يصلي في مكانه الذي صلى فيه الفريضة. وفعله القاسم. ويذكر عن أبي هريرة رفعه لا يتطوع الإمام في مكانه. ولم يصح.
