This is a Nasheed called Muhammad Nabeena, played so often in shops in Makkah and Madinah, especially the ones that sell Islamic CDs and Tapes.  I heard this yesterday after a long time and it bought back the memories of Hajj and Umrah.  Very touching and makes you long to be standing once again in the Masjid of the Prophet صلى الله عليه وسلم .
