Assalamu alaikum,
Jazakum Allahu khayran for your careful attention to the recitation and for reporting this issue.
We understand your concern regarding the Madd of the letter Meem (م) at the beginning of Surah Ali 'Imran (3:1).
To help us investigate, could you please confirm
which reciter
you're listening to and whether you're using the Quran.com website, Android app, or iOS app
?If possible, a short audio or screen recording showing where the recitation cuts off would also be helpful.
This will help us check the specific recording and determine whether any correction is needed.
