Grave

Pious servants of Allah are granted gifts from Allah including intercession for believers. These gifts from Allah (SWT) depends in the degree of that servant in front of Allah. We don't talk to the grave but to the pious servant of Allah who is granted an everlasting life as we read in Quran ( Don't think those who were killed in the way of Allah as dead, nay, there are alive but you do not feel)( Sura 3, verse 169).

'Every believer who dies with the love of Ahlul Bayt, die as a Shaheed. This is according to authentic Hadeeths in Shia and Sunni books including Tafseer of Zamajhshari and Tafseer Al-Fakhr Al-Raazi and many other Sunni books.

Wassalam.

Yes. They know when we visit their graves and feel happy because of our visiting their graves and reciting Quran and praying for them. They hear us when we talk to them. The Hadeeth says: Talk to the dead people in their graves and raise your voice talking to them and tell them: You went before us and we are following you soon. يا أهل الديار من المؤمنين والمسلمين، أنتم لنا فَرَطٌ وإنّا بِكُم إن شاء الله وشيكاً لاحِقون

It is highly recommended to say when you visit the graves of the Muslims: Peace upon you, O people of Laa Ilaaha Illallah السلام عليكم يا أهل لا إله إلا الله.

How did find Laa Ilaaha Illallah كيفَ وَجَدتُم قَولَ لا إلهَ إلّا الله

Wassalam.

Allah is The Most Merciful Who showers His Mercy on us all the times. He wants us to avoid sinful acts and never insist on wrong, so that He forgives our sins when we sincerely repent and seek forgiveness. Sinners who insist on doing wrong and never care to repent, will face the results of their own deeds. Allah's Mercy does not allow punishment for sins we have repented, nor repeating a punishment which has already been given.

The Mercy and Forgiveness of Allah, is above our imagination. His Mercy and Forgiveness will be on The Day of Judgement for almost every one except the enemies of Allah, the Prophet and Ahlul Bayt. Enemies of Allah will be facing the results of their crimes in their graves and in the Day of Judgement as well, but sinners who are not enemies of Allah will not suffer twice. Grave for some believers is a place of purification so they suffer in the grave to go pure in The Day of Judgement.
We need to have more hope in Allah's Mercy and keep ourselves away from sins and seek forgiveness.

Wassalam.

Yes of course. Ziyarat Ashura is a great Ziyarat and it is recommended to recite it every day. Reciting it on behalf of a deceased will make the deceased get great reward as well as the reciter himself.

Wassalam.

The grave of the pious believer is a part of Paradise. Read in Quran how the believers are best received by the angles when they die. (Those pious believers whose souls are taken by the angles, saying to them: Peace be upon you) (Sura 16, Verse 32).

Also you can read in in Sura Al-Waqi'a how the believers get peace and happiness when they die. (Sura 56, verse 90.)

Doing good deeds will make your grave a part of Paradise especially fulfilling your obligatory Prayers on time, paying charity,v helping people who are in need, performing Night Prayers, Ziyarat Ashura, remembering Allah and reciting Quran, etc.

No fear on the obedient servants of Allah (SWT) as we read in Quran ( Those who say: Our Lord is Allah and remained straight and pious, on them shall be no fear, nor shall they grieve)  Sura 46, verse 13.

Death of the believer is the best moment is his life because he will transferred from life of challenges to a life of mercy of Allah (SWT).

Keep reciting ALLAHUMMA SALLI 'ALA MUHAMMAD WA AALI MUHAMMAD. اللهم صل على محمد وال محمد 

as many times as you can. It will enlighten your life and your grave.

'Keep on reciting ASTAGHFIRULLAH RABBI WA ATOOBU ELAYH,أستغفر الله ربي وأتوب إليه 

as it purify us and cleans us from sinful acts.

Have great hope in the Mercy of Allah. Surely Allah is The Most Merciful.

Wassalam.

Those who were been martyred in the way of Allah are alive ( Sura 2, verse 154 and Sura 3, verse 169). No doubt that the martyrs listen to us when we talk to them. In fact, every dead person can hear us when we talk to him loudly as the Prophet (SAWA) spoke to the dead Kafirs who were killed in the battle of Badr.

Martyrs have real life in which they can listen. Regarding the letters, it depends on the status of the martyr. Letters written to the Infallible Imams will be seen they them and might be even replied, but that is not for every martyr.

'Wassalam.

Many authentic Hadeeths stated that every persons will see during his death the Prophet (SAWA) and Ali (AS) and will get the good news of the happiness if he is sincere believer, or will see the bad result of his bad deeds if he was non believer. Al-Shaikh al-Sadouq narrated in his book al-Amaali أمالي الصدوق the statement from Ali: YA HAARA HAMDAN MAN YAMOT YARANI يا حار همدان ٬من يمت يرني O Harith of Hamdan, everyone who dies will see me.

Beside the fact that the sincere believer will see and get good news from Imam Ali (AS) on the moments of death, it is also confirmed that some very sincere and pious believers are been visited by the Infallible Imams in their grave to help them and remove hardships of grave from them. This is mentioned  for pious believers who are :

- Very nice to their parents and relatives.

 - Who recite Ziyarat Ashura every day.

- Who perform Night Prayer .

-Who sacrifice their wealth and comfort in the way if Allah.

- Who sacrifice their life in the love of Allah, the Prophet and Ahlul Bayt (AS).

- Who avoid sinful acts for sake of Allah.

and many other acts of pious and obedience of Allah.

Wassalam.

Barzakh is the world after this world which starts from death and goes on till the day of Judgment. It is mentioned in Quran (There is a Barzakh after their death till the day of they will be resurrected) (Sura 23, Verse 100).

Barzakh includes the grave but it is wider than the grave. Grave starts on burial  but Barzakh starts on death which is before burial.

The pious believer's grave is a garden from the Paradise while the grave of the disbeliever is a ditch from the hellfire, as the Hadeeth states.

Wassalam.

Even if the heirs allow, it is not permissible to dig an existing grave to bury another dead body if the previous dead body still exists in the grave. If the previous dead body has completely decayed and became soil, then it will be permissible to bury another dead body in the grave which has no remaining. In such case, if the land of the grave was purchased by the heirs, their permission is must to bury another dead body in that empty grave.

'Wassalam.

Wassalam.

The grave is the beginning stage of Hereafter (Aakhirah). The grave of the believer is a garden from the Paradise, while the grave of the disbeliever is a part from the Hellfire.

Talqeen which is recited for very dead person mentions the main questions which are: Who is your Lord? Who is your prophet? Who are your Imams? etc.

The questions about the faith are the main questions in the grave. Nevertheless, our deeds will have an effect in out grave. Good deeds will have very good reflection in the grave, while bad deeds will have bad reflection as well.

Wassalam.
