"O Allah, we seek goodness from You and piety from this journey and (the ability to do) good actions by which You are pleased. O Allah, ease this journey for us and make us transverse the road quickly. O Allah, You are our companion in this journey and deputy (guardian) over our household whom we left behind. O Allah, I seek refuge in You from the difficulties of the journey and from seeing bad things and from a bad return at home and household and from the dua of the oppressed".
Note: It is Mustahab to perform two rakaats Nafl Salaat before commencing a journey.

"In the name of Allah, it moves and stops. Definitely my Lord is forgiving and merciful and the Kuffar have not recognised Him as they should, whereas on the Day of Qiyamah the whole earth will be in His fist and the skies folded in His right hand. He is Pure and Superior (lofty) from the belief which the Mushrikeen hold (have)".
"O Allah, You are the Lord of the seven skies and all the things that are under these skies and the seven planets and whatever is over these and of Satan who misled and all those misled by him and for the wind and all that it blows. Thus we seek the good of this town and the good of its members (people) and seek refuge from its evil and the evil of its members and from the evils of whatever is in it".
(Hisnul Hasin from Ibn Habban)
When entering any city or a populated area recite the following dua three times:
اللَّهُمَّ بَارِكْ لَنَا فِيهَا
"O Allah, You grant us good in it (the city/populated area)".
"Oh Earth, your Lord, and my Lord is Allah. I seek refuge in Allah from the evil (of your nights) and those evils created in you and that which moves in you and seek refuge in Allah from the lions, snakes, scorpions and from the evils of the dwellers of the city and from the father and children".
"The heaven has heared our praise of Allah and also heard our testification that He favours us and keeps us in good condition. Our Lord stay with us and grant us your favours and I make dua to seek refuge from Allah from Jahannam (hell fire)".
(Hisnul Hasin from Muslim etc)
It is also narrated that this dua be recited three times in a raised voice.
(Hisnul Hasin from Mustahab)
Prophet Mohammad (S.A.W.) stated that if a person on journey refrains from worldly affairs in his heart and focuses his attention to Allah and remembers Him, the angels stay with him throughout the journey and if he recites imaginary poetry or does any futile thing then Satan stays with him during his journey.
Prophet Mohammad (S.A.W.) told Jabir bin Mutim (R.A.) to recite the following five Suras when on journey:
1- Surah Kaafiroon
2- Surah Nasr
3- Surah Ikhlaas
4- Surah Falaq
5- Surah Naas
Every Surah should commence with "Bismillah" and Surah Naas should end with "Bismillah" as well, thus reciting "Bismillah" six times.
Jabir (R.A.) states: "When I went out on journey (and although I was wealthy and had more merchandise than my companions), my conditions were worse than them, but from the time I began reciting these surahs, on return my condition was better than all of them, and I had most provisions of the journey".
Etiquettes on returning from a journey
When returning from a journey one should sit on the mode of conveyance and recite:
"There is none worthy of worship besides Allah who has no partner, His is the Kingdom and to him is all praise, for He has created everything. We are those returning, repenting and obedient to Allah, performing Sajda, praising Allah, Allah has made truth (fullfilled) His promise and aided His servant and defeated the enemy armies Alone."
On the return journey when entering one's own city recite
"We are returning, repenting and obedient to Allah, praising Him".
Prophet Mohammad (S.A.W.)'s blessed habit was to return from a journey during chast time within the city. He would first go to the Masjid, perform two rakaats Salaats. Thereafter he would stay in the Masjid for a little while and then go home.
Prophet Mohammad (S.A.W.) loved to journey on Thursdays.
