Rules of Tajweed [Merged]

Re: Rules of Tajweed

^^ Its not really a tajweed rule, actually it is a tajweed exception, where a single length dhamma on the end of the word at'amah*u* followed by inantum illa fi is pronounced as a triple length dhamma. There should be a waw madda in this area as a hint for this dhamma on the ha to be stretched.

I am not however, clear on the reason why this is the case, it could be because simply it is just the rule exception for that particular recitation or it could have a meaning linked with the meaning of the verse. I was hoping you could tell me why.
