spiritual ranks and elevation

وَتِلْكَ حُجَّتُنَآ ءَاتَيْنَـٰهَآ إِبْرَٰهِيمَ عَلَىٰ قَوْمِهِۦ ۚ نَرْفَعُ دَرَجَـٰتٍ مَّن نَّشَآءُ ۗ إِنَّ رَبَّكَ حَكِيمٌ عَلِيمٌ

And that was Our [conclusive] argument which We gave Abraham against his people. We raise by degrees whom We will. Indeed, your Lord is Wise and Knowing.
