Eesalus-Sawaabis not only for the deceased; it is also for the living – and is established from the Sunnah as well.
We should therefore also convey the rewards of our optional deeds to the entire Ummah of Rasulullah(Sallallaahu ‘alayhi wasallam), which includes those who are living.
Moreover, when the rights of a Muslim have beenunintentionally violated, it would be a sign of sincerity, that besides asking for forgiveness, the person conveys the reward of some good deed as ‘Eesalus-Sawaab’ to the person who was wronged.
For example : If the person was party to Gheebah (backbiting) and did not prevent it, then besides asking Allah Ta’ala to forgive, the person could read the ‘Quls’or give something in Sadaqah (charity) and send the reward as Eesaalus Sawaab to the person whose right was violated.
If the person has come to know of what was said about him (or her), then the person’s forgiveness should be sought as well.
Of course, this does not mean that we violate people’s rights, using this as an atonement and compensation. A Muslim is careful not to cause hurt or injury to others.
 Eesalus Sawaab : to convey the reward of a good action or charitable deed to another person, alive or deceased. The recitation of Surah Al-Ikhlaas, Surah Al-Falaq and Surah An-Naas - which begin with the word ‘Qul’. These are the last 3 Surahs of the Qur`aan Shareef
