Did all the Prophets bring the same Message of Tawheed? Please provide me with details of it with Qur'an and Hadith.

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions. Calling people to Tawheed (Monotheism/worshipping Allah alone) is the call undertaken by all the Prophets, as the Qur'an states. Allah, the Exalted, Says: And verily, We have sent among every Ummah (community, nation) a Messenger (proclaiming): "Worship Allâh (Alone), and avoid (or keep away from) Tâghût (all false deities, etc. i.e. do not worship Tâghût besides Allâh)….[16:36]. Allah also Said: And We did not send any Messenger before you (O Muhammad SAW) but We inspired him (saying): Lâ ilâha illa Ana [none has the right to be worshipped but I (Allâh)], so worship Me (Alone and none else).[21:25]. There are many other verses stating this issue as well. Allah knows best.
