What to say when leaving the home
 

"بِسْمِ اللهِ، تَوَكَّلْتُ عَلَى اللهِ، وَلَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللهِ".

16. Bismillaahi, tawakkaltu 'alallaahi, wa laa hawla wa laa quwwata ‘ illaa billaah.

In the Name of Allah, I have placed my trust in Allah, there is no might and no power except by Allah.

Reference: Abu Dawud 4/325, At-Tirmithi 5/490. See also Al-Albani, Sahih At-Tirmithi 3/151

"الَّهُمَّ إِنِّي أَعُوذُ بِكَ أَنْ أَضِلَّ، أّوْ أُضَلَّ، أَوْ أَزِلَّ، أَوْ أُزَلَّ، أَوْ أَظْلِمَ، أَوْ أُظْلَمَ، أَوْ أَجْهَلَ، أَوْ يُجْهَلَ عَلَيَّ".

17. Allaahumma 'innee 'a'oothu bika 'an 'adhilla, 'aw 'udhalla, 'aw 'azilla, 'aw 'uzalla, 'aw 'adhlima, 'aw 'udhlama, 'aw 'ajhala 'aw yujhala 'alayya.

O Allah, I seek refuge in You lest I misguide others , or I am misguided by others , lest I cause others to err or I am caused to err , lest I abuse others or be abused, and lest I behave foolishly or meet with the foolishness of others.
