[Pooya/Ali Commentary 72:19] Abdullah, the servant of Allah, is one of the titles of the Holy Prophet. The reference may be to the rough treatment which the Holy Prophet received at the hands of the unruly mob at Taif. The pagan Quraysh used to put all sorts of obstacles in his way to prevent him from preaching the religion of Islam (worship of Allah only) and denouncing idol worship. They used to ridicule him, persecute him and make the physical conditions of his life as difficult for him as possible. The Holy Prophet was sent to deliver the message the final word of Allah, to mankind. He did not force them to follow the right guidance. It is left to the free will of every individual to do as he chooses. If any man decides not to follow the right guidance, he shall be a loser in the hereafter where he will see clearly that the promise of Allah is true, and that those who were considered weak on this earth will be the strong ones. As the Holy Prophet always carried out the commands of Allah in letter and spirit, no matter how much the odds were against him, he is addressed as the servant of Allah-Abdullah.
