Q. We know that the Du’aa for leaving the house: “Bismillaahi tawakkaltu ‘alallaah; Lalaa haula walaa quwwata illaah billaah,” guarantees safety over those things and those people we leave at home, na’m? But, I also heard that this Du’aa guarantees safety over the journey you undertake and success over whatever (halaal) thing you will be doing when you reach your destination. Also it guarantees a safe return home. Is what I heard true?
