Sunnah of the Prophet - Do'a When Leaving The Home

When the Prophet (pbuh) would leave his home, he would say:

بسم اللَّهِ، توكَّلْتُ عَلَى اللَّهِ، اللَّهُمَّ إِنِّي أعوذُ بِكَ أنْ أَضِلَّ أو أُضَلَّ ، أَوْ أَزِلَّ أوْ أُزلَّ ، أوْ أظلِمَ أوْ أُظلَم ، أوْ أَجْهَلَ أو يُجهَلَ عَلَيَّ

"Bismillah, tawakaltu 'ala Allah. Allahumma innee a'oothu bika an adhil aw udhal, aw azil aw uzal, aw adhlim aw udhlam, aw ajhal aw yujhal 'alayy"

‘In the name of Allah, I place my trust in Allah. O Allah, I take refuge with You lest I should stray or be led astray, or slip or be tripped, or oppress or be oppressed, or behave foolishly or be treated foolishly.’

[Abu Dawud & Tirmidhi]
