" You will be going to Christians and Jews(ahl al- Kitaab), so the first thing you should invite them to is the assertion of the oneness of Allaah"*

itu kata2 Rasulullah saw kepada Mu'aadh bin Jabal semasa dia dihantar oleh baginda sebagai Gabenor Yemen pada 9AH..

dari situlah perkataan tawheed di derived kan kerana perkataan 'tawheed' itu sendiri tidak ader di dlm al-Quran or Hadeeths..tetapi content dier tu ader in d Quran
