Verses of Holly Quraan related to Al-Imam Al-Mahdi a,s

Allah, the Blessed and the High says in the Holy Quran:
'O you who believe! Be patient and excel in patience and remain steadfast and be careful of (your duty to) Allah, that you may be successful.'
Surah Aale Imran, Verse 200
In the interpretation of the above verse, Hafiz Qunduzi Hanafi, the famous scholar of the Ahle Sunnah, narrates a tradition from Imam Baqir (a.s.) in his book 'Yanabiul Mawwadah' pp. 5-6,
"Be patient in complying with the obligatory acts and remain steadfast against the cruelties and oppression of enemies and establish contact with your Imam, Imam Mahdi al-Muntazar the Awaited One.
A similar exegesis is also narrated from Imam Sadiq (a.s.), which is mentioned in various books like 'Ma'anil Akhbaar', 'Tafseer-e-Ayyaashi', 'Usul-e-Kafi', etc. Imam Saadiq (a.s.) says:
'Be patient concerning your religion and be patient against your enemy and establish contact with your Imam'.
Tafseer al-Meezan, by Allamah Tabatabai, pg. 201
There is no doubt that Allah, the Blessed and the High desires that His creatures on the earth should be in touch with His Proof and their Imam in every moment of their life. History is a witness to the fact that in the past, people failed to establish contact with Imam of their time. As a result, they could not acquire his recognition and consequently, refused to accept the caliphate of Hazrat Ali (a.s.), threw arrows on the bier of Imam Hasan (a.s.) and brutally killed Imam Husain (a.s.) in Karbala.
Each and every Imam (a.s.) was tortured and oppressed. The light of guidance did not reach the hearts of the people. As time went by, the situation turned for the worse. Today Muslims are living in a situation where there is no recognition of Imam and the true Islam. In fact, in the name of religion and justice, irreligiousness, injustice and oppression is widespread in Islamic society. Islam, which had come to enliven the people, has itself become lifeless. Imam Reza (a.s.) says in this regard:
'May Allah bless the one who enlivens our affairs."
The narrator inquired, 'How are your affairs enlivened?' Imam (a.s.) replied,
"By learning our traditions and teaching them to the people."
Thus, according to the above quote of Imam Reza (a.s.), Islam can be enlivened only through the acquisition of knowledge as subscribed by the Ahle Bait (a.s.) and acting upon it. For this, it is essential that one remains steadfast on his religion and maintains contact and relations with the Imam of his time and at the same time, prepare the ground for others to acquire the same knowledge.
