The ruling on praying the rawatib (regular voluntary prayers) between Maghrib and 'Isha' when combining the prayers by advancing them

The questioner : What is the ruling if one combines Maghrib and 'Isha' and prays the rawatib (regular voluntary prayers) between them, combining by advancing them and praying the rawatib between them? O Khalid.

The Shaykh : According to the author's view, the combination is not valid (sahih) due to the separation between the two prayers, because of the separation between them. Well done, that is fine.
