It is permissible for the Imam after finishing Salah to depart from the right or the left side. It is authentically reported on the authority of
Ibn Mas`ud that he said:
None of you should give Satan any of his prayer by thinking that it is mandatory for him to depart (after finishing the prayer) from his right side only; I have seen the Prophet (peace be upon him) often leaving from his left side.
These are the wordings of Al-Bukhari.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
