In The Name of Allah, The Most Merciful, The Bestower of Mercy..

Indeed diverting from the methodology of the prophets in Dawah is (tantamount) to deviation towards misguidance and destruction. This is because Allah, The Blessed and Most High, laid down and ordained this methodology for all the Prophets.

If the people have Shi’aaraat (i.e. distinguishing principles, doctrines, calls, slogans), we do not have except the Shi’aar (distinguishing principle, doctrine, call) of the Prophets.

If the people have methodologies, we do not have except the methodology of the Prophets, peace and blessings of Allah be upon them.

The Qur’an is the greatest testimony and Allah has often repeated these testimonies and reiterated them in many of the verses.

وَلَقَدْ بَعَثْنَا فِى كُلِّ أُمَّةٍ رَّسُولًا أَنِ ٱعْبُدُوا۟ ٱللَّهَ وَٱجْتَنِبُوا۟ ٱلطَّٰغُوتَ

And verily, We have sent among every Ummah (community, nation) a Messenger (saying): “Worship Allah (Alone), and avoid (or keep away from) Taghut (all false deities, etc. i.e. do not worship Taghut besides Allah).” [An-Nahl: 36]

Every Messenger said this to his nation and appeared to his people with this call – the call to Tawheed–and to turn away from Taghut.
