Entering a Town or City
اللَّهُمَّ رَبَّ السَّمَاوَاتِ السَّبْعِ وَمَا أَظْلَلْنَ، وَرَبَّ الْأَرَضِينَ السَّبْعِ وَمَا أَقْلَلْنَ، وَرَبَّ الشَّيَاطِينِ وَمَا أَضْلَلْنَ، وَرَبَّ الرِّيَاحِ وَمَا ذَرَيْنَ، أَسْأَلُكَ خَيْرَ هَٰذِهِ الْقَرْيَةِ وَخَيْرَ أَهْلِهَا وَخَيْرَ مَا فِيهَا، وَأَعُوذُ بِكَ مِنْ شَرِّهَا وَشَرِّ أَهْلِهَا وَشَرِّ مَا فِيهَا
Allahumma rabbas-samawatis-sab'i wa ma azlaln, wa rabbal-aradinas-sab'i wa ma aqlaln, wa rabbash-shayatini wa ma adlaln, wa rabbar-riyahi wa ma dharayn. As'aluka khayra hadhihil-qaryati wa khayra ahliha wa khayra ma fiha, wa a'udhu bika min sharriha wa sharri ahliha wa sharri ma fiha.
O Allah, Lord of the seven heavens and all they shade, Lord of the seven earths and all they carry, Lord of the devils and all they lead astray, Lord of the winds and all they scatter: I ask You for the good of this town, the good of its people and the good of what is in it, and I take refuge with You from its evil, the evil of its people and the evil of what is in it.
What it means
Arriving somewhere new is a moment of both excitement and exposure. This dua answers it by first calling on the Lord of everything above, below and in between, so that the unfamiliar place is put in proportion before you ask for its good and refuge from its harm.
When and how
Say it once when you first see the town or city you are travelling to, or when you arrive in a new place.
Its virtue
It is recorded among the duas of travel in Hisnul Muslim, gathered from the narrations of the Prophet ﷺ on what to say when a new settlement comes into view. We have not listed a hadith number here because we are not certain of the exact reference.
