Is it permissible to deduct a small monthly amount from one's salary for charitable projects with the intention of including deceased parents and grandparents, as well as one's wife, children, siblings, paternal uncles, and maternal uncles in the reward, and to seek success, blessings, and provisions for the afterlife? And is this considered an act of upholding kinship ties (silat al-rahim)?

It is permissible to donate a monthly sum with the intention that its reward be shared between the donor and their living and deceased family members. This falls under the granting of the reward of charity, which is agreed upon as permissible and whose reward reaches the deceased.

Any act of worship performed by a Muslim, and its reward is dedicated to a deceased Muslim, will benefit the deceased. These acts of worship include supplication (du'a), seeking forgiveness (istighfar), charity (sadaqah), and fulfilling obligations. This is the view held by the majority of jurists.

Imam Al-Shafi'i, however, holds that only the reward of charity, supplication, and seeking forgiveness reaches the deceased, basing his argument on the Almighty's saying: "And that man will not have but what he strove for" (Quran 53:39) and the Prophet's (peace be upon him) saying: "When a person dies, all his deeds come to an end except for three: a continuous charity, or knowledge from which benefit is gained, or a righteous child who supplicates for him."

In conclusion, the reward of charity reaches the deceased by scholarly consensus, as do supplication and seeking forgiveness.
