(Al Hadeed) 57 : 11
مَنْ ذَا الَّذِي يُقْرِضُ اللَّهَ قَرْضًا حَسَنًا فَيُضَاعِفَهُ لَهُ وَلَهُ أَجْرٌ كَرِيمٌ
Who is there to lend to Allah a best loan so that He will increase it in manifold to him, and he has a noble reward.
The mode of giving best loan to Allah is to utilize all favors including wealth, time, and influences in order to propagate Adhikr-the Splendid Book mentioned in verses 41: 41-42-amomg the mankind irrespective of nation, religion, caste, colour, sex, etc. By doing so he is helping Allah so that Allah will help him back as explained in verses 22: 40; and 47: 7. Thus one can become forerunner to the Paradise. See explanation 4: 85; 36: 11-12; and 53: 39-40.
