Bismillaah ... on behalf of the staff team:

The linguistic meaning of ‘Raum’ is ‘The request’. The tajweed definition is the weakening of the sound with a vowel until most of its sound disappears with that weakening. It is also defined as using part of a vowel.

The scholars have determined that the weakening of the sound with a vowel, or reciting with part of a vowel is one third when stopping with ‘Raum’. More is removed from the vowel than that which remains when reciting with ‘Raum’. The sound is weakened due to the shortening of its time.

Stopping with ‘Raum’ can be on:
• dhammah of conjugated and fixed dhammahs.
• kasrah of conjugated and fixed kasrahs.

It does not matter if the letter stopped on is with or without a shaddah, whether the last letter is a hamzah or not, or whether it is a tanween or not.

If there is a tanween however, it must not:
• "Maftoohah"; meaning it must not have a fat-ha.
• “Ism Maqsoorah”; (a word with a tanween ending with alif maqsoora).

*The tanween in both of these cases is changed into an alif when stopping.

*‘Raum’ cannot be on a fat-ha whether it is conjugated or fixed and it also cannot be on a presented kasrah or dhammah put on a letter to get rid of the occurrence of two saakin letters juxtaposed.

Sheikh Ash-Shatabee described ‘Raum’ as:
• “And your ‘Raum’ is listening to your vowel when stopping”.
• “With a hidden sound every close one {can hear}”.

3 differences between 'Raum' and 'Ikhtilaas' are:

‘Raum’:
• 1/3 of the vowel is used. The amount of vowel that went is more than what remains.
• It can only be when stopping at the end of a word.
• Can only be in fixed dhammah and kasrah (not presented) vowels.

‘Ikhtilaas’:
• 2/3 of the vowel remains. The amount of vowel that remains is more than what has left.
• Not when stopping at the end of a word; but can be at the end when continuing or in the middle of a word.
• Can be in all three vowels, conjugated or not.
