require repetition except for "kullama" (whenever). Abu Bakr mentioned regarding "mata" (when) that it also requires repetition because it is used for repetition, as evidenced by his saying: "Whenever you approach him, yearning for the light of his fire, you will find the best fire with the best of keepers." Meaning: at every time. And because it is used in the condition and the reward (jaza'), and whenever the condition is found, its reward is necessitated by it. The correct view is that it does not require this, because it is a noun for time meaning "at any time" and "if," so it does not require what they themselves do not require. The fact that it is used for repetition in some instances does not prevent it from being used for other meanings, such as "idha" (if/when) and "ayy waqt" (at any time), for they are used for both meanings. Allah the Almighty said: {And when you see those who engage in [offensive] discourse concerning Our verses, then turn away from them until they enter into another conversation.} {And when those who believe in Our verses come to you, say, "Peace be upon you."} {And when you do not bring them a sign, they say, "Why have you not contrived it?"} The poet said: "A people who, when evil reveals its canine teeth to them, they march toward it in groups and individually." Likewise, "any time" and "any era" are used for repetition, and the other particles are used for conditional reward, except that since they are used for repetition and otherwise, they are not construed as requiring repetition unless there is evidence for it; the same applies to "mata."

Section: If the reward (jaza') for these particles precedes them, it does not require a particle in the reward, such as his saying: "You are divorced if you enter the house." But if the reward is delayed, it requires a "fa" particle in the reward if it is a sentence consisting of a subject and predicate, such as his saying: "If you enter the house, then you are divorced." It is specific to the "fa" because it is for sequence (ta'qib), so it connects the reward with its condition and indicates its following it. If
