Imam al-Mahdi

This is a very important question for those who really care to improve themselves and achieve better degrees of success in this life and hereafter. These are few practical steps which can make the believer more close to Imam-e-Zamana (AS). More piousness leads to more nearness to Imam-e-Zaman. To add to our Taqwa (Piousness), these are few points:
1. Asking yourself before any act or word whether Allah (SWT) likes it or not? That is the best degree of remembering Allah (SWT) along with continuous remembering him in our heart and tongue.
2. Reciting Quran and Du'a with understanding and pondering and gifting its reward to Imam Al-Mahdi (AS).
3. Performing Nawaafil prayers especially Night Prayer ( SALAT ALLAYL or NAMAZ E SHAB) every night.
4. Talking to Imam e Zaman (AS) every day and night as he listens to us and responds to the pious believers. 
5. Gifting the reward of all our good deeds to Imam Al-Mahdi and all Ahlul Bayt (AS) which will not only multiply our reward, but also make us more near to them.
6. Having best Akhlaq (Manners) with parents, relatives especially your family members and with all people.
7. Being with Wudhu all the times as much as you can.
8. Trying to strengthen our will power by avoiding evil desires and performing good acts even if it can look like difficult like fasting, charity,etc. We need to control our desires and never allow our desires to control us.
9. Helping needy people in any possible way for the sake of Allah (SWT).
10. Trying to make believers happy by respecting them, caring for them, smiling in their faces and in any other act of generosity and kindness to them or their families.
11. Performing obligatory Prayers on time with out any delay. Imam Al-Mahdi (AS) performs every Prayer on time, so, your praying on time will make your Prayers elevated to Allah (SWT) with the Prayer of Imam Al-Mahdi (AS).
12. Keep your most important supplication and wish, the reappearance of Imam Al-Mahdi (AS) and sincerely pray for him more than praying for yourself and your family.

Anti Christ is a misleading person who will be killed by Al-Mahdi (AS). Jesus Christ (AS) will come down from the sky to this earth and will join Imam Al-Mahdi (AS) as one of his supporters and will pray behind him.

The government of Imam Al-Mahdi (AS) will last very long as we read in the narrations that: The rule of the Justice will long as much as the injustice ruled.

The person who claims such claim needs to read more about Imam Al-Mahdi (AS) who is the divine leader who will establish the world government of peace and justice for all human beings.

Wassalam.

The Imam Al-Mahdi (AS) will have when he will re appear ten thousand sincere assistants who will lead  and help people all over the world, out of them 313 will be the most pious and most sincere and most able to help the aim of the Imam (AS).
The 313 assistants will be regular individuals or scholars or leaders who have that high degree of sincerity and dedication to Allah (SWT). Many of them will be unknown to people because their sincerity stops them from seeking publicity, name or fame but known to Allah (SWT) as very humble and dedicated and pious. They will be men and women as well and from different parts of the world.

Wassalam.

Seeing Imam Zaman (AS) is not a matter which can be achieved by just Du'a, but it needs purification of heart and deeds to reach to real piousness. Real pious servants of Allah,v can see Imam Zaman (AS) because of their continue piousness.

Do more good deeds like Reciting Quran, giving Sadaqa, helping in good cause, etc) and gift the reward to Imam Zaman. This can make us more near to him (AS).

Wassalam.

from AllahYes. It is highly recommended to recite Quran and do good deeds on behalf of the Prophet (SAWA) and his Holy Progeny. Our great Ulama advise to recite Quran daily and gift the reward of it to Imam Al-Mahdi (AS). You will then get greater reward and more generous gifts from him.

It should be noted that reward of reciting Quran or any good deed can be gifted not only to the deceased ( Marhoumeen) but also to the living persons.

Wassalam.

Yes of course. Humble servants of Allah (SWT) can be males or females. Imam Al-Mahdi (AS) meets, guides and helps servants of Allah, where ever and when ever Allah wants him to help. Many sincere females were been blessed with this bounty in many places and times. Piousness degrees are never restricted to any gender.

Allah says in Quran : Whoever does good whether male or female while being true believer, We will grant them righteous life and will grant them reward for the best of they were doing. (Sura 16, verse 14).

Allah (SWT) Has sent revelation (Wahi وحي) on the mother of Musa (Sura 28, verse 7) because she was a Pious female.

Wassalam.

These claims from this person prove that he is a liar. He has been appointed and financially supported by our enemies to create dispute and cause trouble among the followers of Ahlul Bayt. Fortunately, his lies are clear for our community and after spending huge amounts of money which is been injected by our enemies,he hardly has any considerable following. 
He claimed that he is son of imam Al-Mahdi, while people of Basra where he belongs to, know the name of his father and grand father and his family tree and confirm that he is a liar.

There are special websites and social media groups refuting his lies.

'Wassalam.

Dajjal is the last leader of falsehood, will come before the reappearance of Imam Al-Mahdi (AS). He will be killed by the last leader of righteous, Imam Al-Mahdi (A.S.). Dajjal is one of the definite signs of the reappearance of Imam Al Mahdi (A.S.). Dajjal will lead an army of the enemies of Ahlulbayt and fight against Imam Al-Mahdi (A.S.) and he will be defeated. (Al Amali by Al Toosi, Page 459). It is mentioned in Kamaal Ad-Din Page 336 from Imam Jafar As-Sadiq (A.S.) that Imam Al-Mahdi (A.S.) will kill Dajjal. Unfortunately, we read narrations in some Sunni books, which are taken from Non-Muslims and it go against the Truth. For example, the narration in Sahih Muslim which is called Hadeeth Al-Jassasa Volume 8 Page 204 & Hadeeth in Sahih Al Bukhari about Ibn Sayyad who is according to the narration of Bukhari the Dajjal. Ibn Hajar Al-Asqalani in Fath Al-Bari Volume 13 Page 276 confirmed his opinion that Dajjal is still alive. We don’t have in our authentic narrations the exact date when Dajjal was born and in fact we don't need it, but we only need to know that Dajjal is a devil satanic leader and he will lead his followers to the hellfire, and he will fight against Imam Al-Mahdi (A.S.) and he will be killed by Him.  (Al Amali by Al-Toosi Page 527, Al- Bihar Volume 76 Page 74, Al-Waafi Volume 26 Page 186).

Wassalam.

Yes, it is mentioned in many narrations that Imam al-Mahdi (AS) will martyred and Imam Husain (AS) will pray his Namaz e Janaza. (Biharul Anwar , volume 53, page 103 and Al-Kafi 8:250)
