This division of Tawheed into three is not from
The Messenger of Allah صلى الله عليه وسلم or from Sahba or first few generation of Muslim.. ...........Some Scholars has divided into two some as Three
These teminologies are from scholars for understanding purpose.
So saying that if someone is not using these term that means his tauheed is weak is not CORRECT and acceptable.
Sahabas Imaan was most strong and they didnot used these three types.)
However in Tabligh there are People of different
ranging from Mufti and Alim scholars like Mufti Mahmoodul Hasan and Maulana Yusuf kandhalvi but also simple people who even learn Attahiyat and four Surah and start from Tajweed and kalima or may be learning reading Quran.
So depending on this their level of knowledge scholary talk and refrence to quranic ayats and ahadith will certainly differ.
And this is normal in sahaba also some were very big Alim like Hazrat Abukar,Umar,Ali ,abdullah ibne massod,abdullah ibne abbas and others RAZIALLAH ANHUMA AJMAEEN but
MOST OTHER sahaba were ordinary muslim not Master of knowledge.
Terminologies role is there but the faith and Emaan should be strong and correct that is foremost.
More to emphasise that we see in India and pakistan that where tableegh work is strong grave worship is weak.
Where Tabligh work is weak Grave worship and bidats are strong. I have seen it not only in cities but even among families and friends families.
This gives live and practical example that tablighi Jamaat is for tauheed correct Aqeeda and Strong Emaan.
All are requested to co operate.We should be kind for our muslim fellows.(Allah knows the best).
