The audio says Saamia-tin which's wrong in this context. The correct pronunciation is Saamia-tun. In Arabic, diacritics change depending on which part of speech the word is and its position in the sentence. Also, the little circle above the letter m is wrong, it's actually كَسْرَة Kasrah (the small diagonal line below a letter).

The pronunciation is slightly off in this sentence, expected from beta course, hopefully it'll be fixed soon
