عَنْ أُمِّ سَلَمَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ إِذَا خَرَجَ مِنْ بَيْتِهِ قَالَ بِسْمِ اللَّهِ تَوَكَّلْتُ عَلَى اللَّهِ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ أَنْ نَزِلَّ أَوْ نَضِلَّ أَوْ نَظْلِمَ أَوْ نُظْلَمَ أَوْ نَجْهَلَ أَوْ يُجْهَلَ عَلَيْنَا
It is narrated from Sayyida Umm Salama (may Allah be pleased with her) that when the Noble Prophet (peace and blessings be upon him) would leave the house, he would recite this supplication: Bismillah, tawakkaltu ‘ala Allah, … … aw yujhala ‘alayna (In the name of Allah, I place my trust in Allah. O Allah! I seek Your protection from slipping, or being led astray, or committing injustice, or being wronged, or acting ignorantly, or having ignorance imposed upon us).
