Mukhtasar Bukhari (Abridged) 669 — It is Sunnah to hasten the funeral

Narrated by Abu Huraira (may Allah be pleased with him) from the Prophet (peace and blessings of Allah be upon him) that he said: "Hasten with the funeral, for if it was righteous, you are bringing it closer to good, and if it was otherwise, then it is an evil which you are removing from your necks."
