Does the deceased see, hear, and feel what is happening in this world when visited? Is placing palm fronds on the head of the deceased and watering them prescribed or an innovation? Does a woman's visit to a grave to recite Qur'an invalidate her Hajj?

The dead seeing those who visit them is an unseen matter for which no evidence has been established. As for the dead hearing the words of the living, scholars have differed on this, and the correct view is that they do hear. There are narrations indicating that the dead meet and question each other, and that the deeds of the living are presented to them. As for placing palm fronds on the grave, there is a difference of opinion on this, and the preponderant view is that it is not prescribed. As for pouring water on the grave, it is permissible if the intention is to help the soil settle, but sprinkling it when visiting is an innovation. Watering palm fronds is not prescribed. Women are permitted to visit graves for admonition, provided they do not fall into prohibited acts, and this has no effect on the validity of Hajj. The reward for reciting the Quran reaches the deceased, but without specifying the recitation at the grave.
