فَإِذَا بَلَغَتْ خَمْسًا سَائِمَةً، وَحَالَ عَلَيْهَا الْحَوْلُ: فَفِيهَا شَاةٌ إِلَى تِسْعٍ.
Translation: Once the camels number five, are grazing livestock, and a year passes, one sheep is due through nine camels.
“Five grazing camels” incorporates the opening threshold and the condition of grazing; the qualifying year must also have passed. From 5 through 9, the due amount is one sheep.
Requiring a sheep instead of a camel is part of the transmitted zakat schedule. Having 6, 7, 8 or 9 camels does not trigger another sheep.
