The sunnah prayed before and after should be 2×2 and not one continuous
prayer.

Sheikh my question in previous email was the number of rakahs for dhur are 4 sunnah 4 fard 2 sunnah but if i pray 4 sunnah 4 fard 4 sunnah because i read the hadith that whoever prays 4 rakah after dhur prayer(i.e:fard) Allah will protect him from hell. So these last 4 sunnah if i perform them do i need to perform last 2 sunnah separately?
