Mad Wajib Muttasil
Meaning: 
Obligatory Connected Elongation
Explanation: 

Mad Wajib Muttasil, extra elongation of the vowel which precedes a glottal stop (hamzah ء) in the same word, such as Maa' ماء (water) and Suu' سوء (something bad).

In Qur'anic recitation, the vowels should be made extra long (4 or 5 times the length of a short vowel); the above words become Maaaaa' and Suuuuu'.
