Famous Hadith:
"People walked up to the Prophet, asking, 'How can we serve God?' The Prophet answered, 'You want to serve God, then serve Humanity!'."
The Messenger of Allah said, “Allah is in the assistance of His servant as long as His servant is in the assistance of others.” [Muslim (2698) and others, on the authority of Abu Hurayra (Allah be pleased with him)]
This is totaly in line with the Quranic Message:
13:17 He sends down water from the height causing the riverbeds to flow
according to their measure and the flood bears on its surface swelling foam.
And, when they use fire to refine metals for their jewelry or equipment, foam is produced like it. In this way God is citing for you the example of the Truth and the Falsehood. For, as far as the foam is concerned, it passes away as scum upon the river banks - While what is of benefit to mankind, abides on earth. (The real existence on earth is of the person or the system that benefits humanity) This is how God uses analogies for you to understand.
