With the name of Allah Most Gracious, Most Merciful
Sura 42 (Shura-Consultation)
Calling to the universal message
V15: “Now then, for that (reason), call (them to the Faith), and stand steadfast as thou art commanded, nor follow thou their vain desires; but say: “I believe in the Book which Allah has sent down; and I am commanded to judge justly between you. Allah is our Lord and your Lord: for us (is the responsibility for) our deeds, and for you for your deeds. There is no contention between us and you. Allah will bring us together, and to Him is (our) Final Goal.”
The instruction provided is to hold fast to the commandments of Allah (SWT) and invite others to it. A clear distinction is required separating human wishes and desires from the ultimate Truth. Furthemore we are instructed to provide the clarification presented through the Quran but without compelling anyone to follow the path prescribed by Allah. The final decision is that of Allah (SWT).
Cross reference – Sura 16 Verse 64: And We sent down the Book to thee for the express purpose, that thou shouldst make clear to them those things in which they differ, and that it should be a guide and a mercy to those who believe.
