Aqa Abdu'r Rahim was a native of Bushruyih and a fanatical Muslim. He was very disturbed by seeing people becoming Bahá'ís.  One day he went to the local mulla (clergyman) and asked: "What are we to do with the Bahá'ís?"  The mulla answered: "Whoever kills the Bahá'ís shall go to the best places in paradise."  Aqa Abdu'r Rahim began thinking about killing a few Bahá'ís so that he could go to heaven. 

One day he took his gun and descended upon an old Bahá'í man by the name of Haji Baba.  Aqa Abdu'r Rahim told Haji Baba: "As you are a Bahá'í, I have come to kill you."  Haji Baba replied: "No problem, but now that you want to kill me, let us first talk together a little."  Gradually the words of Haji Baba affected Abdu’r Rahim.  Instead of taking Haji Baba’s life, he decided to investigate the truth.  Haji Baba took him to the house of the sister of Mulla Husayn of Bushruyih (the first disciple of the Báb).  Aqa Abdu'r Rahim spoke with the Bahá'ís for one and a half days without sleep or rest and eventually declared his belief in Bahá'u'lláh.  The Bahá'ís told him that Bahá'u'lláh was still alive and imprisoned in the prison of Akka.  Aqa Abdu'r Rahim decided to go on pilgrimage to the presence of the Blessed Beauty.

The distance between Iran and Akka is long.  It took Aqa Abdu'r Rahim six months to reach Akka.  It had not been long since Bahá'u'lláh had been exiled there and the authorities were very strict.  The prison guards were not to allow anyone to enter the fortress.  For the Bahá'ís it was very difficult even to enter the city of Akka.  Aqa Abdu'r Rahim somehow managed to get into the city.  He first went to the seashore and washed himself and his clothes.  Then, since he knew he would not be allowed into the fortress, he decided to circumambulate it.  He began to pray and ask God to find a way for him to attain the presence of Bahá'u'lláh.  Suddenly he saw a hand from the prison window beckoning him to come inside.  He realised that Bahá'u'lláh was calling him.  Although he knew that everywhere there were many guards, he paid no attention to them.  He thought to himself: "If Bahá'u'lláh has summoned me, I must go in."  So he went towards the fortress and passed the guards.  None of them stopped him.  They did not even see him!  Aqa Abdu'r Rahim reached the cell of the Blessed Beauty and entered it.  Bahá'u'lláh said: "We closed the eyes of the guards so that you may come to Our presence."  Thus Aqa Abdu'r Rahim succeeded in attaining the presence of Bahá'u'lláh in prison.

When he was about to be dismissed Bahá'u'lláh gave Aqa Abdu'r Rahim a few Tablets to take to the believers in Persia.  On the way back to Iran, when Aqa Abdu'r Rahim was in Baghdad, a policeman became suspicious of him.  Aqa Abdu'r Rahim realised that they wanted to arrest him.  If he were arrested they would take the Tablets from him and would destroy them and probably imprison him too.  He said a prayer in his heart and asked God to protect the Tablets.  Then he just threw the Tablets into a shop and continued to walk on.  The policemen arrested him and took him to the police station.  There they asked him a number of questions and when they realised he was a stranger and a good person, they released him.  Aqa Abdu'r Rahim returned to the market place immediately and went slowly towards the shop.  He waited until the people had gone.  Then he quietly approached the shop.  The shop owner called him in.  When he went in the shop owner embraced him and warmly greeted him with the greeting of :"Allah'u'Abha"!  It so happened that the owner of the shop was a Bahá'í.  Aqa Abdu'r Rahim realised that of all those shops in the market of Baghdad, it had been the will of God that he should pass by the only Bahá'í shop so that the Tablets may not be destroyed.  After receiving hospitality, he set off towards Persia and delivered every single one of the Tablets to their intended recipients.

Revelation of Bahá'u'lláh vol. 3

This story illustrates a number of points:

1. The potency of the Word of God in transforming human souls.  Thus, a potential murderer was transformed into a servant of humanity. 
2. The importance of a goodly character and kindly tongue when teaching the Faith.  Thus, `Abdu’r Rahim was met with utmost kindness and calmness and non-violence when he intended to show violence to his perceived enemy.
3. The leaders of religion, have in every age, been chiefly responsible for holding the people back from recognising the truth of the new Revelations of God.  Instead of encouraging independent search after truth, they have often kept the people in ignorance and encouraged blind obedience and belief in superstitions, which have bred prejudices.  Prejudices have been the source of misunderstandings and wars throughout history.
4. The power of the Manifestation of God – in breaking the laws of nature and performing miracles.  Thus, the guards did not see the man passing through the gate. 
5. The Manifestation of God has the power to both avoid imprisonment and to make all people believers in the twinkling of an eye.  However, He has consented to be imprisoned and has allowed the pure in heart to recognise the truth through their own effort and with their own free will.
