In these series of articles we focus on verses that are intended to say something about Imam Mahdi who is the Last Savior.
God in surah al-A’raaf, verse 159 states, “And of the people of Moses there is a party who guide to the truth and do justice according to the truth.” «وَ مِن قَوْمِ مُوسىَ أُمَّةٌ يهَْدُونَ بِالحَْقِّ وَ بِهِ يَعْدِلُونَ»
It is narrated from Imam Saadiq (the Shia sixth Imam) who have said:
يَخْرُجُ مَعَ الْقَائِمِ ع مِنْ ظَهْرِ الْكُوفَةِ سَبْعٌ وَ عِشْرُونَ رَجُلًا خَمْسَةَ عَشَرَ مِنْ قَوْمِ مُوسَى ع الَّذِينَ كَانُوا يَهْدُونَ بِالْحَقِّ وَ بِهِ يَعْدِلُونَ وَ سَبْعَةٌ مِنْ أَهْلِ الْكَهْفِ وَ يُوشَعُ بْنُ نُونٍ وَ سَلْمَانُ وَ أَبُو دُجَانَةَ الْأَنْصَارِيُّ وَ الْمِقْدَادُ وَ مَالِكٌ الْأَشْتَرُ فَيَكُونُونَ بَيْنَ يَدَيْهِ أَنْصَاراً وَ حُكَّاماً
“(At the time of the Upriser’s advent) twenty seven individuals from Kufa (will return back to life and) will be raised with him (and they are) fifteen people from the nation of Moses those who guided to the truth and did justice according to the truth, seven people form the Companions of the Cave, Joshua, Salmaan, Abu Dojaanah al-Ansaari, al-Miqdaad, Malik bin Ashtar. They will be present with him and will be chosen as the assistants and rulers.
This point that some individuals will return back to life is something that even is pointed to in the Torah as we read in Daniel, 12: 2, “And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.”
The mentioned narration just points to some of these individuals and in other narrations the names of much more are referred to.
This verse with the mentioned narration contains some considerable points:
1- Some people will return back to life in this world: The rising of Imam Mahdi is not limited to a specific time of place. All of those who are qualified from all over of the world and even those who lived in the past will be gathered around him to help him. As a result, those who, in the past, used to guide others and implemented justice in the earth, it is possible for them to be resurrected in this world to see the fruit of their good actions. It also means that these righteous and pious people will see the result of their good actions even in this world prior to the next world.
2- Some people of the previous religions were godly: To be pious and God wary is not limited to those who has come to existence after the advent of Islam. Even some of those who were Jews or Christian, before the emergence of Islamic, were so much qualified that they will be raised to life to help the Imam of the Moslems.
