O YOU who have attained to faith! When you are told, Make room for one another in your collective life", do make room:* [and in return,] God will make room for you [in His grace].* And whenever you are told, Rise up [for a good deed]", do rise up;* [and] God will exalt by [many] degrees those of you who have attained to faith and, [above all,] such as have been vouchsafed [true] knowledge:* for God is fully aware of all that you do.
