1. All the Ulama-e-Haq and the Buzrugaan-e-Deen hold the belief that to send Esaale Sawaab to the souls of the deceased is permissible.
2. It is permissible for a Muslim to send the Sawaab of his deeds, such a Salaah, Saum, Zakaah, Hajj, Sadaqa, etc. to others. (Hidaya)
3. If a person kept Fast, performed his or her Salaah, or gave Sadaqa and then sent this Sawaab to another person, either living or deceased, then to do so is permissible, and that Sawaab reaches the said person. (Bahrur Raa'iq)
4. Hazrat Anas (radi Allahu anhu) asked the Prophet (sallal laahu alaihi wasallam): "If we send Sawaab to the deceased, give Sadaqa and Khayraat and ask Du'a for them, does this reach them?" The Prophet (sallal laahu alaihi wasallam) said: "Verily it reaches them. Read Salaah for them as you read for yourself and fast for them as you fast for yourself. In other words, make Esaale Sawaab of Salaah and Saum for them." The meaning of this Hadith Shareef is that we should send the Sawaab of our actions to the deceased, since in reality one cannot perform Salaah and keep fast for another person or on his behalf, but we can send the Sawaab of our actions to them.
