ثُمَّ أَوْرَثْنَا ٱلْكِتَٰبَ ٱلَّذِينَ ٱصْطَفَيْنَا مِنْ عِبَادِنَا ۖ فَمِنْهُمْ ظَالِمٌ لِّنَفْسِهِۦ وَمِنْهُم مُّقْتَصِدٌ وَمِنْهُمْ سَابِقٌۢ بِٱلْخَيْرَٰتِ بِإِذْنِ ٱللَّهِ ۚ ذَٰلِكَ هُوَ ٱلْفَضْلُ ٱلْكَبِيرُ
Commentary:
After mentioning in verse 25 above that Divine Messengers were sent to all the peoples, and after explaining in the immediately preceding verse (v. 32) that the Quran testifies to the Divine origin of all the Books that were given to those Messengers and fulfils the prophecies that the former Prophets and Divine Books had made about the Quran and the Holy Prophet, the verse under comment proceeds to say that the sacred and onerous duty of preaching this last Divine Message to mankind has been entrusted to men whom God has specially selected for this purpose. They are not men of ordinary calibre. They have fully fitted themselves for the discharge of this great duty by passing through various stages of rigorous spiritual discipline. The following are the three stages through which a believer has to pass to attain a very high degree of spiritual development. In the first stage he wages a veritable war against his low desires and passions, and practises strict self-denial. It is after he has learned to control his passions and suppress his evil desires that he moves on to the next stage of "taking the middle course." At this stage, he does not falter or fall but his progress towards his goal is but gradual. It is at the third and last stage when he has attained his full moral stature that his progress towards the realization of his great goal becomes rapid and uniform. This stage has been termed سابق بالخیرات in this verse.
