Tablighi Jamaat Khurooj Fi Sabilillah Objective Task Purpose

What should be the objective and task during this migration and Motivation.(Tablighi Jamaat Programme)
Maulana Ilyas said (Letter to Maulana Abul Hasan Ali Nadvi page no 21)

“The real preaching is of two things, and the rest all Usools consists only of giving it a definite shape.
1.     One of these things is related to the apparent skeleton of work i.e. revival of the practice of Sahaba travel­ling in batches from place to place and from country to country for the propagation of the Guidance brought by the Prophet Muhammad Sallallahu Alaihi wasallam,

2.     While the second one denotes the Revival of Islamic senti­ments (Jazbat) i.e.  Giving rise, once again, to the practice of laying down one's life at the command of Allah, as has been set forth in the Quran:
فَلاَ وَرَبِّكَ لاَ يُؤْمِنُونَ حَتَّى يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ ثُمَّ لاَ يَجِدُوا فِي أَنفُسِهِمْ حَرَجًا مِمَّا قَضَيْتَ وَيُسَلِّمُوا تَسْلِيمًا (النساء: 65
So, never by your Lord! Never shall they become believers, unless they make you the judge in the disputes that arise between them, then find no discomfort in their hearts against what you have decided, and surrender to it in total submission. [4:65]
وَمَا خَلَقْتُ الْجِنَّ وَالإِنسَ إِلاَّ لِيَعْبُدُونِ (الذاريات: 56
I did not create the Jinns and the human beings except for the purpose that they  should worship Me. [51:56]

The Priority themes to be undertaken in the whole programme
To strive for all the deen brought by the sacred Pro­phet in proportion, to their importance.

In this system of migration and motivation we have to strive for Whole deen i.e all commands of Allah and sunnah path of HAZARAT Muhammad  sallallahu Alaihi wasallam, priority of matters will be in proportion to their importance in deen. To start with the most basic things have to be taken care of first.
