Allah is so great! Allah is so great! Allah is so great! All Glories be to Allah who subdued this (carrier) to us and we were not capable of subduing it and verily unto our Lord, we are to return. O Allah! Make this journey easy for us and reduce its length. O Allah! You are the Companion of the journey and the Trustee of the family. O Allah! I ask for you protection from the tediousness, mishap and adversity of the journey, and distortion and perversion in property, family and off-spring Salat-e-Qasr
