Almuntakhab Fi Tafsir Alquran Alkarim

Mankind was a single ‘Ummah (Nation) of common descent occupying a definite territory. By natural generation, numbers multiplied and were scattered in various directions and became disunited emotionally and mentally. There and then Allah sent Prophets as a spectacle and warning to all. He equipped them with the Book of Truth guiding into all truth in order to judge between people regarding issues of reason. Yet those who disputed its precepts were the same who were given the Book (Ahl Al-Kitab) imparting enough signs guiding them into illumination and mental enlightenment. But they were no longer disposed to the truth due to their mutual enmity and malignant intention. Nonetheless, Allah will guide the truth-seeking believers to His path. Allah guides whom He will to the path of righteousness

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(2:213) In the beginning all the people followed the same way. (Afterwards there came a change and differences arose). Then Allah sent Prophets to give good tidings to those who followed the Right Way and warnings to those who swerved from it. And He sent down with them the Book based on the Truth so that it should judge between the people concerning their differences. (Differences arose not because people were not given the knowledge of the Truth in the beginning, nay), differences arose between those very people who had been given clear teachings, and (for no other reasons than that) they wanted to tyrannize over one another. *230 So Allah, by His leave, guided those who believed in the Prophets to the Truth about which they had differed; AIIah guides whomever He pleases to the Right Way.

*230). When ignorant people attempt to trace the history of 'religion' they tend to the view that man began his life in the darkness of polytheisrn and that in the course of time, corresponding to man's progress, this darkness gradually receded and light increased till man arrived at monotheism.
The Qur'anic version, however, proclaims that man began his life in full light of the Truth. God revealed this Truth to the very first man He created, one to whom He intimated the right way of life for man. Thereafter the human race remained on the Right Way for some time and lived as one community. Later, however, people invented deviating ways. This did not happen because Truth had not been communicated to them. The cause was rather that some people wilfully sought to acquire privileges, benefits and advantages beyond their legitimate limits, and thus subjected others to injustices. It was in order to enable people to overcome this corruption that God sent His Prophets. These Prophets were not sent to found separate religions in their own names and bring new religious communities into existence. Rather the purpose of the Prophets was to illuminate before people the Truth which they had allowed to be lost, and once again make them into one community.

ابتدا میں سب لوگ ایک ہی طریقہ پر تھے (پھر یہ حالت باقی نہ رہی اور اختلافات رونما ہوئے) تب اللہ نے نبی بھیجے جو راست روی پر بشارت دینے والے اور کج روی کے نتائج سے ڈرانے والے تھے، اور اُن کے ساتھ کتاب بر حق نازل کی تاکہ حق کے بارے میں لوگوں کے درمیان جو اختلافات رونما ہوگئے تھے، ان کا فیصلہ کرے (اور ان اختلافات کے رونما ہونے کی وجہ یہ نہ تھی کہ ابتدا میں لوگوں کو حق بتایا نہیں گیا تھا نہیں،) اختلاف اُن لوگوں نے کیا، جنہیں حق کا عمل دیا چکا تھا اُنہوں نے روشن ہدایات پا لینے کے بعد محض اس کے لیے حق کو چھوڑ کر مختلف طریقے نکالے کہ وہ آپس میں زیادتی کرنا چاہتے تھے پس جو لوگ انبیا پر ایمان لے آئے، انہیں اللہ نے اپنے اذن سے اُس حق کا راستہ دکھا دیا، جس میں لوگوں نے اختلاف کیا تھا اللہ جسے چاہتا ہے، راہ راست دکھا دیتا ہے
