Assalamu Alaikum Wa Rahmatullah
Is it permissible to delay the Salatul janazah and burial of the deceased for the son of a deceased to reach the Janazah?
This delay would be at least 12 hours.

It is disliked to delay the Salatul Janazah or the burial procedure unless there is a genuine reason to do so.
This is due to the hadith of the Prophet (peace be upon him) where he said,” Hasten the burial.
Only Allāh Ta’ālā knows best
