The Holy Quran expressly declares that the human race is one family. All of us are the children of Adam and Eve, whether our skin is white or black. At various places it says: “All human beings are a single nation” (2:213). “All human beings are naught but a single nation and yet they disagree” (10:19). “And verily this your nation (human beings) is a single nation” (21:92) and (23:52).
Man is born with a heart of compassion which reacts in accordance to the feelings of fellow humans. Compassion, love, affection and care are the innate qualities which make a human. These qualities define man. The development or suppression of these qualities entirely depends on man himself. From time to time, philosophers and religious scholars have tried to encourage people to increase these innate qualities in themselves. Humanity is one such aspect which has been stressed upon in all parts of the world. "Service to Mankind is service to God" is the proverb highly prevalent all over the world. Serving and treating fellow human beings with courtesy and kindness is an essential part of a good moral conduct. All world religions share and support this concept. Islam make make it a religious duty to serve and be of service to humanity.
Islam has put much emphasis on serving humans, but providing merely food and shelter to fellow humans cannot be considered as a service to Allah (SWT) on the whole. It is inappropriate to think that we are serving mankind as a whole by simply spending a huge amount in charity. We need to be more and more active in helping others and giving out of love from what we love to others .
