Al-Rabii
Most often the nisba to Rabīʿa, the great ʿAdnānī grouping the genealogists set beside Muḍar. It is also the nisba to al-Rabīʿiyya, a village of the al-Qaṭīf oasis, and is built on the ordinary name Rabīʿ and on Rabīʿa sections elsewhere. It settles nothing on its own.

Overview
Al-Rabii (al-Rabīʿī) is met most often as the nisba to Rabīʿa, one of the two great divisions the genealogists set on the ʿAdnānī side beside Muḍar, and the parent grouping under which they place ʿAbd al-Qays, Bakr, Taghlib and much else. That is the sense in which the name is overwhelmingly borne, and it is the reason this page is written as a tribal nisba rather than as a village name.
Why the form settles nothing
The difficulty is that several unconnected origins produce the same word.
The first is Rabīʿa itself, in the broad sense above. But Rabīʿa is not a single ancestor's name used once: the genealogists record men called Rabīʿa in many lines and sections called Banū Rabīʿa in tribes that have no connection with the ʿAdnānī grouping, and the nisba to each is written identically. So even a source that means a tribal Rabīʿa may not mean the great one.
The second is the ordinary personal name Rabīʿ, and the ordinary word behind it. Ibn Manẓūr's entry under r-b-ʿ is a wide one: al-rabīʿ is the season of growth and the rain that brings it; al-rabʿ is a dwelling and the people who stop on it, from rabaʿa, to stay in a place; al-marbaʿ is the ground where the spring is passed. Bynames are built on all of these, and on the given name, with no tribal sense at all.
The third is a place. Al-Rabīʿiyya is a village of the al-Qaṭīf oasis on the al-Khaṭṭ coast, and the nisba to it lands on the same shape. Places of that name are not confined to this coast either.
Said plainly: al-Rabīʿī is consistent with the ʿAdnānī grouping, with a different Rabīʿa, with a personal name, with a season and with a village, and nothing in the written form chooses between them. Only a source that says which is meant will do it.
Reading the name
Where Rabīʿa is meant, the narrower nisbas of its branches say more — those of Bakr, of ʿAbd al-Qays and of the sections under them are informative in a way this one is not. A source that gives one of those is worth more than a source that gives al-Rabīʿī.
Bearing the name
A tribal nisba records what a family is called, not who its ancestors were. It may follow descent (ṣarīḥ), alliance (ḥilf) or clientage (walāʾ), and only a family's own documented record tells those apart. This page describes a historical grouping and the names formed on the word, and makes no claim about any modern family.
