1. Sayyidina Ibn Mas‘ud Radiyallahu ‘Anhu reports, Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam said: "Daawud ‘Alayhis Salaam said: ‘O Allah, what is the reward of the person who carries a dead person to his grave seeking Your pleasure’. It was said: ‘His reward will be that my Malaa’ikah (angels) will carry his Janaaza, and they will supplicate on his ruh together with other (pious) ruhs’". – Ibn Asaakir, (Sharhus Sudur).

Commentary:

That which has been narrated in this narration that the person who takes part in carrying and burying a deceased person, his reward will be that the Malaa’ikah will accompany his Janaaza. The object is that more angels will accompany him, otherwise the Malaa’ikah accompany all Janaaza. Briefly, in the ahadith of chapters eight, nine and ten the honour and respect stated for a Muslim mayyit (deceased) is clear. The skies weeping at the end of a Muslim’s life. Every possible gravesite of the earth wishing that a Muslim be buried therein. How great is his honour before the Malaa’ikah. They accompany his Janaaza like troops and battalions. Such respect and honour given by the Malaa’ikah, who are a great creation of Allah, to a person, is not a trivial thing. In the world, this is not accorded to the greatest of kings. It is a thing to ponder about, when the deceased observes that I am so greatly honoured and respected, how much will he appreciate the hereafter, and regard the world as wretched and despicable. What a good fortune will he regard the leaving of this world and going to the hereafter? It is said regarding such things: ".... For this let (all) those strive who strive for bliss". - Surah At-Ta ftiif, (Mutaffifiin), 26. and "For the like of this, then, let the workers work". -Surah Saaffaat, 61.

Up to here those aspects have been stated that occurs before burial. Some aspects that will take place are left for later, like the ruhs meeting one another, and becoming beloved of the earth etc.
