It is narrated from Sayyiduna Ali (may Allah be pleased with him) that when the Prophet (peace and blessings of Allah be upon him) intended to set out on a journey, he would recite this supplication: «اَللّٰهُمَّبِكَأَصُولُوَبِكَأَحُولُوَبِكَأَسِيرُ» "O Allah! I attack with the blessing of Your name, I move with the blessing of Your name, and I walk with the blessing of Your name."
