According to a tradition related to Imam Moosa Ibne Ja’far (a.s.) that
a person who wishes to go on a journey should stand in the door of his house facing towards the destination of journey and recite Alhamd and recite the following:
اَللّٰهُمَّ احْفَظْنِي وَ احْفَظْ مَا مَعِيَ وَ سَلِّمْنِي وَ سَلِّمْ مَا مَعِيَ وَ بَلِّغْنِيْ وَ بَلِّغْ مَا مَعِيَ بِبَلَاغِكَ الْحَسَنِ الْجَمِيْلِ
allaahummah fazneee wah-faz maa ma-e’ya wa sallimnee maa sallim maa ma-e’ya wa ballighnee wa balligh ma ma-e’ya be-balaaghekal hasanil jameele.
O Allah! Keep me and all the things with me safe and sound and let them reach the destination safely.
The person who precedes on a journey in the above manner the Almighty God will be looking after his welfare and of those and things who are with him, and he will reach safely his destination InshaAllah.
