The Prophet (sallallaahu 'alayhi wa sallam) said:
"Surely there is in the body a small piece of flesh; if it is good, the whole body is good, and if it is corrupted, the whole body is corrupted, and that is surely the heart." (Bukhari)
The Messenger of Allah said: When a person dies, his actions come to an end, except for three things: a continuing Sadaqa (charity), knowledge from which benefit is still being derived, and a righteous child who prays for her or him (translated meaning from Muslim).
"On the day of Resurrection the Qur'aan will petition Allaah to cloak the one who was a companion if the Qur'aan [recited it often] with garments of honour and respect.
A crown of honour will then be placed on the head of the reciter.
The Qur'aan will then petition Allaah to shower his pleasure on the reciter.
Allaah will then become pleased with him.
The reciter will then be asked to recite the Qur'aan, thereby attaining higher ranks of elevation.
In reward for each ayah, a good deed will be given to him."
