Jareeda are fresh twigs (without leaves) cut from a tree.
A lot of emphasis has been given by our Aimma, to place jareedas on both sides of the mayyit. The reason given, that as long as the twigs remain green, the mayyit will be safe from 'fishare qabr' (the squeezing of the grave).
It is better to use the twigs of a date palm, if not available then twigs from a pomegranate tree. However, if these are not available then twigs from any tree will suffice.
The twigs should be of arms length and the twig on the right side should touch the armpit. The twig on the left side should be kept above the armpit.
The overall 'chadar' is then wrapped around the mayyit.
