Rabb
Rabb has three meanings: (i) Lord and Master; (ii) Sustainer, Provider, Supporter, Nourisher and Guardian, and (iii)Sovereign and Ruler, He who controls and directs. God is Rabb in all the three meanings of the term. The rational of the basic Qur'anic message - 'serve none but God' - is that since God is man's Rabb - Lord, Sustainer, Provider, Nourisher, etc. He alone should be the object of man's worship and service.See, for example, Qur'an 2:21.

Rahim
Rahim is from the root rhm (rahm) which denotes mercy. In the Qur'an this attribute of God has been used side by side with Rahman (which is also from the same root rhm). As such Rahim signifies God's mercy and beneficence towards His creatures. Moreover, according to several scholars, the word Rahim signifies the dimension of permanence in God's mercy.
Rahman
Rahman (literally 'merciful') is one of the personal names of God. According to scholars of the Arabic language and some commentators of the Qur'an, the word has the nuance of intensity regarding Divine Mercy. Thus the word does not just signify the One Who has mercy; it rather denotes the One Who is exceedingly merciful; the One Who is overflowing with mercy for all. Ar-Rahman: Surah 55 of the Qur'an.
