Desire of Vision of Allah (Divine Vision) is one of the Obligatory Practices of Mahdaviat. 

• Hz Imamuna Mehdi e Maud ^AS in his sayings said, ” Talab e Deedar e Khuda Farzat –To Seek Vision of Allah is obligatory.”
• Some of the companions of Imamuna Mehdi e Maud ^AS have ascertained that a believer (mumin) is he who sees Allah with his physical eyes (sar ki ankh), or eyes of Heart (dil ke ankh) or in dream (khaab), or the person who seeks to achieve this attribute. Even if he may not have seen Allah in any of these modes described above, he is included among the believers (mumins).   
  [The reason for this being Allah rewards His believers based on their intention for good deed rather than if the good deed has been completed or not.]
• Many Ahadith of Prophet Muhammed ^SAWcan also co-related to this obligatory Practice. 
• Prophet Muhammed ^SAW has said that on a person, who engages himself in perpetual remembrance of Allah, He opens the doors of His Knowledge (ma’rifat), fills his heart with the illumination of His Light and Secrets. All the veils between him and Allah are removed, so much so that he sees Allah manifest in the world.
• Quoting Allah, Prophet Muhammed ^SAW has said, “When My remembrance and his indulgence in Me dominates My servant, I grant him pleasure and enjoyment (lazzat) in My remembrance, and when he relishes pleasure and enjoyment in My remembrance. he becomes My lover (ashiq) and I become his (ashiq). And I remove all the veils between him and Me.”
  
• Again quoting Allah, Prophet Muhammed ^SAW has said, “I peep into heart of My servant and (when) I find that My remembrance dominates his heart, I become his (sense of ) hearing, which he hears,  his (sense of) seeing (basarat) with which he sees; I become his hand with which he grips (thing); I become his leg, with which he walks; and when he asks Me for something. I grant him (what he asks); and when he supplicates Me, I accept his supplications.” 
• Prophet Muhammed ^SAW has said quoting Allah that  “If My Zakirs (those who are engaged in the remembrance of Allah) knew what bounties they have missed by not being near Me, they would have laughed little and wept profoundly; if those who are near Me knew what they have missed by not having My love, they would have wept tears of blood; if those who are unmindful of Me knew what bounties they are missing by not achieving My zath (essence), they would have cut their veins. “

• Remembrance of Allah (Zikrullah) is one of the obligatory practices of Mahdaviat.

  One of the sayings (Naql e Mubarak) of Imamuna Mehdi e Maud ^AS is, “Koshish e Zikr be-kuneed. Make an effort to remember (Allah).”
  

• The importance of Remembrance of Allah can also be proved by Verses of Quran and Ahadith of Prophet Muhammed ^SAW.

   

• Prophet Muhammed ^SAW said, “Should I not inform you about a deed which is best (in the eyes) of your Lord, and which is more chaste than all deeds, which improves your ranks, which is better than giving silver and gold in charity and mutual killings between you and your enemies?” His companions asked, “O Messenger of Allah! What is that deed?” The Prophet said, ” It’s the Remembrance of Allah, which is the head of all (good) deeds, and which is better than all the deeds.“
• Prophet Muhammed ^SAW has said as quoted in Mudarik, ” When your tongue is soaked in Allah’s remembrance, you remain separated (alaheda –solitude) from this world.”
•  
• Two most important timings as per the Practices of Imamuna Mehdi e Maud ^AS was to sit with his Jama’at (followers) in Dairah in Zikrullah primarily two times i.e. 1. After the Fajr Prayers till Sunrise and between Asr and Magrib prayers. These two timings are called Sultan ul Lail (King of the Night)
  Sultan un Nahar (King of the Day).
  Those who have performed Mediation during these two   timings are rewarded equivalent to mediation performed throughout the day.

   

One of the obligatory practices of Mahdaviat is Saubat e Sadiqheen, which is to remain in the company of truthful.

As humans we tend to be influenced by people who are close to us or whose company we spent most of our lives with. If we stay in company of bad people we will unknowingly adopt their bad habits and we exhibit those traits in ourselves. Hence Imamuna Mehdi e Maud ^AS teachings ascertain to stay in company of truthful.

• Allah said to Hz Zakariya ^AS, ” Then did the angels call to him, even while he stood praying in the sanctuary (mihrab) …” Where he confined himself and prayed to Allah day and night.
• And in the story of Mary, as per Surah Mariyum in Holy Quran”.…Every time that he (Zakariya ^AS entered (her) chamber to see her, he found her supplied with sustenance. He said, ” O Mary! Whence (comes) this to you? ….
• Hz Jabir bin Abdullah ^Rz has narrated that Prophet Muhammed ^SAW stayed at the cave of Hira for month. He did come out of the solitude of the cave only for ablution, congregational prayers or friday prayers.
• Hz Abu Muslim ^Rz said that the Prophet Muhammed ^SAW liked seclusion because it gave freedom from the worries and anxiety. He used this freedom for remembrance of Allah and wondering about the attributes of Allah. This seclusion also helped him distance himself from human relationships and gave humility to his heart (Khushu o khuzu).
• Hz Imamuna Mehdi e Maud ^AS (the Perfect Follower of Prophet Muhammed ^SAW) revived this important practice of Prophet Muhammed ^SAW, where his followers would remain in the Dairahs and followed “Hudood e Dairah”. People living outside of Dairahs were called “Bahar wale” (outsiders) even today.  

One of the most important obligatory practices of Mahdaviat is Trust in Allah. 

“…And lay your trust in Allah if indeed ye are men of faith” –Quran. 
Tawakkal (trust in Allah) means liberating (oneself) from the bondage of all of (Allah’s) Creations (makhluqat), in such a way that one’s sight (ruiyat) should be fixed upon Allah. This means that this is pure and unadulterated slavery of Allah and it is also perfect freedom.
