In the word haa2ulaaa2 there are two madd mutassil as far as I can see, and both should be given the necessary four harakaat in length.
However I notice many reciters making the first part only a short count but lengthening the second part. I.e. haa2 (two count) and 2ulaa2 (four count) - why is this? Or is it a mistake on their part? I have doubted this as well qualified reciters have followed this in their recitation.
Wa alaikum assalaam wa rahmatullahi wa barakatuh,
The word is actually two words, the first being the two letter word for drawing attention and the second the word . The first medd is then because there is an alif at the end of a word and a hamzah at the beginning of the next word. In the reading of Hafs ‘an ‘Aasim min tareeq Ash-Shatibiyyah this can be lengthened 4 or 5 vowel counts, but in Tareeq At-Tayyibah, it can be lengthened two vowel counts.
The second medd is because the medd letter (an alif) is followed by a hamzah in the same word.
Those reading the first medd with two vowel counts and the second medd with four vowel counts are reading from one of the ways of Hafs ‘an ‘Aasim from Tareeq At-Tayyibah.
