Jami` at-Tirmidhi, Book 48, Hadith 58 (In-Book) ⓘ

Umm Salamah narrated that : When the Prophet would leave his house, he would say: “In the Name of Allah, I place my trust in Allah. O Allah! We seek refuge in You from slipping unintentionally or becoming misguided, or committing oppression or being oppressed, or acting ignorantly or being treated ignorantly (Bismillāh, tawakkaltu `alallāh. Allāhumma, innā na`ūdhu bika min an nazilla aw naḍilla, aw naẓlima aw nuẓlam, aw najhala aw yujhala alainā).”

حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ عَامِرٍ الشَّعْبِيِّ، عَنْ أُمِّ سَلَمَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ إِذَا خَرَجَ مِنْ بَيْتِهِ قَالَ ‏ "‏ بِسْمِ اللَّهِ تَوَكَّلْتُ عَلَى اللَّهِ اللَّهُمَّ إِنَّا نَعُوذُ بِكَ مِنْ أَنْ نَزِلَّ أَوْ نَضِلَّ أَوْ نَظْلِمَ أَوْ نُظْلَمَ أَوْ نَجْهَلَ أَوْ يُجْهَلَ عَلَيْنَا ‏" ‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
