Salvation promised for Four Communities having faith and good deeds
In the second verse (69), Allah Almighty addresses four traditional religious communities, persuades them to have faith and act righteously whereupon He promises salvation for them. The first of those are: الَّذِينَ آمَنُوا (those who believe) that is, the Muslims. Secondly: الَّذِينَ هَادُوا (and those who are Jews); thirdly : صابِئُونَ (the Sabians); and fourthly: نصَارَىٰ (the Christians). Three of these Communities - Muslims, Jews and Christians - are well-known and found in most parts of the world. Any community having the name Sabian does not exist today. Therefore, scholarly opinion varies as to their exact identity. Quoting Qata-dah, the Tafsir authority, Ibn Kathir has reported that Sabians were people who worshipped angels, offered prayers contra-oriented to the Qiblah and recited the Scripture, Zabur (revealed to Sayyidna Dawud) (علیہ السلام) .
The context of the Qur'an seems to support it as the four Scriptures mentioned in the Qur'an are Torah, Zabur, Injil and Qur'an. Thus, named here are the believers in these four Books.
Another verse on the same subject, almost in the same words, has appeared in the seventh Section of Surah al-Baqarah:
اِنَّ الَّذِينَ آمَنُوا وَالَّذِينَ هَادُوا وَالنَّصَارَىٰ وَالصَّابِئِينَ مَنْ آمَنَ بِاللَّـهِ وَالْيَوْمِ الْآخِرِ وَعَمِلَ صَالِحًا فَلَهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ ﴿62﴾
Surely, those who believed, and those who are Jews, and Christians, and the Sabians - whoever believes in Allah and in the Last Day, and does good deeds - they have their reward with their Lord. And there is no fear for them nor shall they grieve. (2: 62)
Other than the place-oriented transposition of some words, there is no difference between them.
With Allah, Distinction Depends on Righteous Deeds
The gist of both these verses is that distinctions of lineage, home-land, and nationality do not matter in the sight of Allah. Anyone who takes to total obedience, faith and good deeds as a way of life - no matter what he has been before - shall find himself acceptable with Allah and his devotion will bring the best of appreciation from his Creator. And it is obvious that total obedience after the revelation of the Qur'an depends on being a Muslim - because, there are instructions to this effect in the past Scriptures of the Torah and the Injil as well, while the Qur'an itself was revealed for this particular purpose. Therefore, after the revelation of the Qur'an and the appearance of the Last among Prophets , (علیہم السلام) it cannot be correct - without believing in the Qur'an and having faith in the Holy Prophet ﷺ - to follow either the Torah or the Injil or the Zabur. Thus, these verses would mean that whoever from among these communities becomes Muslim shall become deserving of salvation and reward in the Akhirah (Hereafter). Provided right here is the answer to the doubt as to what would happen to all their dark doings of sin and disobedience and disbelief and anti-Islam and anti-Muslim mechanizations once they have become Muslims? The disarming answer is: All past sins and short-comings will …
