If a person performs salat near graves, the dead sees him and understands that he is performing salat and admires him. It may also be noted that the The word 'ziyara' (visit) is used in such hadith ash-Sharif, which would not have been used if the dead had not recognized the person who came to the grave. In all languages and every dictionary, this word is defined as the meeting of people who know and understand one another. And the word "Salamun 'alaikum" is to be said to persons who will understand it.
Do the dead hear what the living say?
Do the souls of the dead meet and see each other?
He replied in the affirmative to all question and produced many prophetic traditions in support. In al-Mutaqaddim he declared: The soul of every deceased is bound to his body in an unknown way. The souls are permitted to affect and dispose (tasarruf) their bodies and be present in their graves. The attachment of the soul to the body will not fade even after the body decays in the grave.
In another Hadith in (Kanzul Ummal by al-Imam al-Muttaqi) it is narrated by Sayyidina 'Ali ® that the Prophet [sal Allahu alayhi wasallam] said: "Whoever goes to a graveyard or passes by a graveyard and recites surat al-Ikhlas eleven times and gives the thawab (reward) of the recital to the dead buried there, will receive the same thawab for it as the dead people. In fact the Prophet [sal Allahu alayhi wasallam] is encouraging us to recite surat al-Ikhlas and present the thawab (reward) of it as a gift to the dead when we visit them.
Then according to a hadith reported in Mishkaat, and narrated by Abdullah Umar ® after the deceased is buried, stand before its head-side and recite the first Ruku of Surah Baqara, i.e. from “Alif Laam Meem” upto “Humud Muflihoon” and recite by its feet the last Ruku of the same Surah from “Aamanur Rasoolu” till “Fansurna alal qumil Kaafireen” i.e. till the end of this Surah.
The Holy Prophet [sal Allahu alayhi wasallam] said: "Recite Sura Ya-Sin for your dead.” (Abu Dawud, Ibn-e-Majah, an-Nasai, Mishkaat - Kitaabul Janaiz). Scholars point out that the hadith is rigorously authenticated by Imam Suyuti (rah.) as well as Ibn Habban. And al-Hafiz Ibn Hajar, when discussing this hadith in al-Talkhis al-Habir, mentioned that Imam Ahmad (rah.) said in his Musnad, "Abul-Mughira informed us that Safwan informed us that the scholars used to say: If it, meaning Ya Sin, is read for the dying, his [death] will be lightened by it. " Strange how some people don’t even like Ya-Sin Shareef being read out for the dead! Hadhrat Daata Ganj Baksh in his Famous Book "Kashful Mahjoob" said: "Do visit the graves of your relatives and beloved and do recite Fatiha and Ya-Sin at their graves, so that they should pray for you." Ibn al-Qayyim mentions in Kitab ar-Ruh: Abu Bakr al-Atrush said: “A man used to visit his mother’s grave every Friday and recite Surah Ya-Sin there. After reciting the Surah one day, he said: ‘O Allah! If you have destined a reward to this Surah, then reward it to the inhabitants of these graves.’ The following Friday a woman approached this man and asked him if he were so-and so. After the man had affirmed it, she said: ‘I saw my dead daughter in a dream. She was sitting by the edge of her grave. I asked her what made her sit there. She said that so-and-so came to the grave of his mother and recited Surah Ya-Sin as a reward to the inhabitants of the graves Therefore, some of its good befell us.”
Muhammad bin Nu'man ® narrates that Rasoolullah [sal Allahu alayhi wasallam] said: "Whoever visits his parents' graves or visits one of their graves every Friday, then he will be forgiven and will be written as being one of the pious" (Mishkat page 154).
Today, some people are saying that making Dhikr at the graves is Bid`a! We have proven it is not so. It is also proven that an ordinary man is able to recite Qur'an in his Qabr and a normal living man is able to hear him. Thus if a truthful person claims that he has been spoken to by a Wali, at the Wali's Qabr, it is most likely true, and most importantly, possible. This fact is grounded in the abovementioned Hadiths. The pious Muslims are in comforts in their life after death. They can very well hear to our call and reply to our questions, as the boy replied to Hazrat Umar ® when he visited his grave as we shall see later.
