Learn Arabic (Modern Standard): هل من شبهة حوله؟ لا، ما من ريب في براءته. - Is there any suspicion about him? No, there is no doubt about his innocence.

This is the redundant من (مِن الزائدة) featured in this lesson. It is used after an interrogative particle like هل or a negative particle like ما, directly before an indefinite noun. It adds strong emphasis, translating well to 'any' or 'whatsoever' in English. Without it, the sentence would just be 'Is there a suspicion? There is no doubt.'

Since من is a preposition, do شبهة and ريب take the genitive case (majrur)?

Yes! Because of the redundant من, you must pronounce both nouns with a genitive case ending (kasratayn): شبهةٍ and ريبٍ. However, functionally, these words are still the subjects of their respective clauses, which would normally be nominative. The redundant preposition changes the ending, but not the deep grammatical role.

Why is 'about' translated as حول in the first question, but as في in the answer?

Arabic prepositions rarely map one-to-one with English; they depend heavily on the noun they attach to. شبهة (suspicion) naturally pairs with حول (literally 'around') to mean suspicion surrounding someone. Conversely, ريب (doubt) typically takes في (literally 'in') to express having doubt in a fact or situation.

Could we use ليس instead of ما for the negation here?
