"Zawwadakallaahut-taqwaa, wa ghofara dzanbaka, wa yassaro lakal khoiro haitsu maa kunta."
(May Allah endow you with taqwa, forgive your sins and facilitate all good for you, wherever you be.)(taqwa: a comprehensive term which refers to all good actions and obedience i.e. performing the commanded actions and avoiding the prohibited actions.)
Translated from Ustadz Firanda Andirja's Indonesian commentary (Bekal Islam). Quoted verses, hadith and duas keep their Arabic; where the commentary gave its own Indonesian rendering of them, that rendering is not translated and is marked [translation not shown].
This dua is said by someone to pray for another person who is about to travel (a musafir). It contains a request that Allah give the traveller the provision of taqwa, forgiveness, and ease in what is good throughout his journey.
