Muslims attain benefit but also the living ones.

The erudite Hanafi jurist, Mufti Amjad ꜤAlī al-AꜤẓamī رَحْمَةُ الـلّٰـهِ عَـلَيْه states:

Īṣāl al-Thawāb, that is, to convey the reward of the Holy Quran or ṣalāt upon the Prophet or Kalimah Tayyibah or the reward of any good deed to other Muslims is permissible. The reward of all monetary and physical forms of worship (monetary worship such as charity, and physical worship such as salah, fasting, etc.), and the reward of farḍ and nafl acts can all be conveyed to others because the deceased receive benefit from the conveying of reward of the living.^[1]

صَلُّوۡا عَلَى الۡحَبِيۡب                                                               صَلَّى اللّٰهُ عَلٰى مُحَمَّد

Dear Islamic brothers! As long as a person lives in this world, his parents, siblings, spouse, children, relatives and friends etc., are with him; they are with him in every trouble and hard times and try to relieve his sorrow. If he is ill, they inquire after him, but when the same person is buried in the dark grave, neither his parents nor his siblings nor family members nor friends nor relatives are with him, rather he is alone in the grave. It is only the deceased who knows whatever happens to him after he has been buried in the grave.

Talking about the reality of the grave, the Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم has said:

اَلْقَبْرُ رَوْضَةٌ مِنْ رِيَاضِ الْجَنَّةِ، اَوْ حُفْرَةٌ مِنْ حُفَرِ النَّار

“The grave is either a garden from the gardens of Paradise or a pit from the pits of Hell.”^[2]

We do not know about the one who is in the grave and whether their grave is a garden of Paradise or معاذاللہ it has become a ditch of Hell for him, but with a desire for doing good to a Muslim, we should form the habit of conveying reward to them.
