And (call to mind the time) when (numerically) you were small (i.e. in the minority, in the Makkan period,) and oppressed in the country (i.e. economically unstable and victims of exploitation). You were (also) afraid that (the powerful) people would snatch you away (i.e. socially too you were neither free nor secure). So, (after migration to Madina He (Allah) provided for you a free and secure abode and strengthened you with His help (through Islamic rule and power) and supplied you with sustenance of pure and wholesome things (through brotherhood, spoils of war and free economy) so that you may give thanks to Allah (by means of absolute submission to Allah’s Commands).
