The comprehensive doa for leaving home is: 'Bismillah, tawakkaltu 'alallah, Allahumma inni a'udhu bika an adilla aw udall, aw azilla aw uzall, aw adhlima aw udhlam, aw ajhala aw yujhala 'alayy' — seeking protection from misguidance, slipping, oppression, and ignorance in all directions.
بِسْمِ اللَّهِ، تَوَكَّلْتُ عَلَى اللَّهِ، اللَّهُمَّ إِنِّي أَعُوذُ بِكَ أَنْ أَضِلَّ أَوْ أُضَلَّ، أَوْ أَزِلَّ أَوْ أُزَلَّ، أَوْ أَظْلِمَ أَوْ أُظْلَمَ، أَوْ أَجْهَلَ أَوْ يُجْهَلَ عَلَيَّ
Bismillah, tawakkaltu 'alallah. Allahumma inni a'udhu bika an adilla aw udall, aw azilla aw uzall, aw adhlima aw udhlam, aw ajhala aw yujhala 'alayy.
Meaning: In the name of Allah, I place my trust in Allah. O Allah, I seek refuge in You from leading astray or being led astray, from causing to slip or being caused to slip, from oppressing or being oppressed, from behaving ignorantly or being treated ignorantly.
Source: Sunan Abu Dawud #5094Doa ini comprehensively covers four pairs of dangers in both active and passive forms: misguidance (leading astray/being led astray), slipping into error (causing/being caused to slip), oppression (oppressing/being oppressed), and ignorance (acting ignorantly/being treated ignorantly). Nabi never left home without it, showing its critical importance for daily protection.
بِسْمِ اللَّهِ، تَوَكَّلْتُ عَلَى اللَّهِ، اللَّهُمَّ إِنِّي أَعُوذُ بِكَ أَنْ أَضِلَّ أَوْ أُضَلَّ، أَوْ أَزِلَّ أَوْ أُزَلَّ، أَوْ أَظْلِمَ أَوْ أُظْلَمَ، أَوْ أَجْهَلَ أَوْ يُجْهَلَ عَلَيَّ
The Prophet (peace be upon him) never left my house without raising his eyes to the sky and saying: 'Allahumma inni a'udhu bika an adilla aw udall, aw azilla aw uzall, aw adhlima aw udhlam, aw ajhala aw yujhala 'alayy.'
