Does the deceased wife see her husband and what he does, and does the reward of reciting the Quran reach her, and what are her feelings when it is recited, and why does she not appear in dreams despite her husband's attachment to her?

The deceased wife does not see her husband in her grave, nor is she aware of his circumstances. It is permissible to recite the Qur'an and dedicate its reward to the deceased, and it is hoped that this will reach her and benefit her. The husband should frequently supplicate for her and give charity on her behalf, and he should manage his affairs according to the dictates of the Sharia. Not seeing her in a dream does not indicate anything.
