Facts about prophecy and the message
Every messenger was from the nation he was sent to and he spoke the same language as them
Of the wisdoms of Allah the Almighty, is that every messenger sent by Him is of the same kind as those who will receive that message.
Moreover, another wisdom is that the messenger speaks the same language as the people he is sent to, so that they understand his words and their meanings.
The infallibility and perfection of the messengers and prophets
Allah’s prophets and messengers are characterized by a perfect mind, sound natural disposition, honesty and by being free of any bodily deformations that are repugnant to the sight or repel sound senses. Allah has purified their souls and morals. They are, therefore, the most perfect of mankind ethically, own the purest of souls and are the most generous in their benevolence. Allah gathered and placed perfect morals, the highest of manners, insight, knowledge, forgiveness, generosity, courage and justice in all of them. Consequently, they excelled in these morals among their people. Messengers are the finest of Allah’s creation, chosen and picked by Him to transmit the message and convey the trust.
Prophet Muhammad (pbuh) was known among his people as As-Sadiqul Ameen (the honest and trustworthy one) even before the message was revealed to him, and thus His Lord described him as:}And verily, you (O Muhammad [sal-Allâhu ‘alayhi wa sallam]) are on an exalted (standard of) character.{(al-Qalam :4)
The messengers and prophets were humans
Those messengers and prophets, despite being described as having sublime characteristics given by Allah, were still humans affected by what affects other human beings. They grew hungry and sick and they slept, ate, married and died.
