The Holy Prophet Muhammad Sallallahu Alaihi Wasallam worked all his life with utmost sincerity for the well-being of his fellow men. He spent all his time, his resources, and his energies on guiding the ignorant people of Arabia to the light of Islam. He was busy day and night in his mission for the betterment of humanity and suffered at the hands of the very people whom he was endeavouring to save from the fire of Hell. He was worried about the plight of the people,who were living in complete ignorance and evil and did not know what was good or bad for themselves. He wanted to save them from a life of evil and misery and bring them back to the ways of goodness and piety. Sometimes he felt sick and hurt at their bitter remarks and strong opposition, but never lost hope or gave way.

At Mecca, he went from house to house to every family and gave them the Message of Allah with great compassion, love and sincerity as their well-wisher, but in return they showered abuses upon him. He did not lose heart but continued to encourage them to the path of goodness. On another occasion, Almighty Allah comforted him in these words:

"We know indeed that what they say, grieves you:it is not you they reject; but the wicked deny the signs of Allah" [Holy Qur'an 6: Ayat 33]

"Ya Rasul! let not those grieve you who run towards infidelity, some of those who say with their mouths, 'We believe'; but whose hearts believe not" (Holy Qur'an 5: Ayat 41) .

His whole life bears witness to the sincerity and love with which he preached the mesaage of Islam. He never asked for any reward from the people for all his efforts towards their welfare and tolerated their abuses and taunts with great patience. No one paid any heed to his sincere and honest message. Some of them, including Abu Lahab, his uncle, abused him but he tolerated everyhting and continued his sincere efforts for the good of the people.

He invited his own family to his place and delivered a short speech in a very impressive way, explaining the basic principles of Islam. Then he said, "O my relatives, I have a brought a thing which will bring prosperity and happiness to you in this world and in the next world". No one except Hazrat Ali Radiyallahu Anhu, who was a boy, supported him. But he was so sincere and honest in his mission that in spite of abuses and hostility, he continued his struggle.

Once the chiefs of Quraish came to him and said, "O Muhammad, you have abused our gods, sown the seeds of disruption and discourse among us, destroyed our solidarity and brought misery and sadnes to all of us, If you want wealth, we will make you the richest man in the country. If you want power and leadership, we will make you our ruler. If you want a beautiful woman just name her,k and she will be yours. If you are sick, we can arrange for the best doctor to cure you". The Holy Prophet Sallallahu Alaihi Wasallam heard all this very quietly and replied,"I do not want any wealth or riches; nor have I any desire to be a king or a ruler; nor do I want any woman; nor am I sick. I am not interested in any of your proposals. I am but a humble servant of Allah, Who has sent me to you as His Messenger to warn you of His punishment if you reject His message, and give you good news if you accept it. If you accept this Message and follow me, you will reap the benefits of this world and the next". He further added," If you place the sun in my right hand and the moon in my left, and ask me to leave my mission in return , this I would not do. I shall continue to do my duty as assigned to me by my Lord".

What greater proof of his sincerity is needed! He rejected all the material wealth and worldly honours offered to him by the Meccan chiefs. He had only to compromise with them on some of his basic principles. If he was not commanded by the Almighty Allah to deliver His messageor if he was not sincere in his mission, he would easily have compromised with his opponents and enjoyed the worldly pleasures of wealth and status. But he was far above these petty attractions and was sincere and devout in his mission. Thomas Carlyle, in his book- Hero-Worship and the Hero in History, speaks of his sincerity in these words: " There was something in this Truth he had got which was of Nature herself; equal in rank to sun or moon or whatsoever thing Nature had made. It would speak itself there, so long as the Almighty allowed it, in spite of Sun and Moon, and all Kuraish and all men and all things. It must be that and could be no other".

"Ah, no! This deep-hearted son of the Wilderness with his beaming black eyes and open social deep soul, had other thoughts in him than ambition. A silent great soul; he was one of those whom Nature herself has appointed to be sincere - no hearsays could hide that unspeakable fact, 'Here am I !' Such sincerity, as we named it, has in very truth something of the Divine. The word of such a man is a Voice direct from Nature's own heart". And Carlyle continues,"A serious, sincere character; yet amiable, cordial, companionable, jocose even - a good laugh in him withal".

Hazrat Muhammad Sallallahu Alaihi Wasallam struggled all his life, through thick and thin for the welfare of the people. He never gained anything materially, socially or politically. He had the good of the people at heart and spent all his life to achieve this in the light of the revelation of Allah. He lived an ordinary life like an ordinary man, doing his household chores, sewing his cloak, mending his shoes, repairing his walls. He sat among the people when he went to the mosque as one of them, without any distinctive position and no one there could recognise who was the Messenger and Ruler. All his life he struggled hard and sincerely for the good of the people, without any ostentatious pride. A cursory glance at his character will show his immense sincerity for the Mission assigned to him by Almighty Allah. And an impartial observer will hardly fail to notice, from almost every incident of his life, his sincere efforts for the betterment of humanity. Above, all this struggle was not for his financial gain or worldly glory, but for the Glory of Allah and the welfare of the people.
