Quranic root
ربع
r · b · ʿ
The root develops three principal orientations: a part or arrangement based on four, remaining or dwelling, and lifting or raising.
From the four-part principle come the numerals, ordinal and fractional terms, distributive forms, four-stranded objects, and fourth-day cycles. From remaining or dwelling come abode, seasonal residence, pasture, and related fertility meanings; from lifting come raising stones or loads, strength, and derived capacity expressions.

Cautions
Points that affect how this root should be read.
The Quranic occurrence count is 22 across six QAC form groups; the public numeral form أَرْبَع combines the nominal and temporal-tagged QAC groups because the lexical item is the same numeral.
Lane reports variant conventions for the fourth-day watering cycle and for the seasons and months called ربيع.
The Quranic use of رُبُع is securely a quarter-share; Lane's related contracted form رُبْع is retained separately in broader Classical coverage where its technical and regional uses are explicit.
Lane's bracketed historical Quran references were not converted into modern verse locations unless the corresponding QAC location was independently supplied.
