The checked printed witness expressly lists four foodstuffs: wheat—half a ṣāʿ; dates—one ṣāʿ; raisins—one ṣāʿ; and barley—one ṣāʿ. These are per outstanding day.
Some searchable transcriptions omit the raisins option, but the inspected printed source includes “aw ṣāʿan min zabīb.” It has therefore been retained rather than silently dropped.
