Upon leaving the mosque

Bismillāhi waṣṣalātu wassalāmu 'alā Rasūlillāhi, Allāhumma 'innī 'as'aluka min faḍlika, Allāhumma`ṣimnī min ash-shaytānir-rajīm. In the Name of Allah, and peace and blessings be upon the Messenger of Allah. O Allah, I ask for Your favor, O Allah, protect me from Satan the outcast. Reference: ibid.
