Is stopping the recitation at the word "yastahyī" (is ashamed/hesitates) in verse 26 of Surat al-Baqarah, and the unintended meaning that results from it, a sin requiring repentance?

Stopping at the word "Allah" is a reprehensible stop (waqf qabih) that suggests a meaning not befitting Allah Almighty, and it is forbidden except out of necessity, such as running out of breath or coughing. If the stop is unintentional, there is no sin in it. However, one who stops due to an excuse should repeat the word or phrase to begin correctly.
