All Messengers bring the same message from Allah. All the Messengers mentioned in the Qur'an demanded essentially the same two things from the communities they were sent to: The people must believe in Allah as the only Lord and, just as importantly, they must respect, fear, and obey Him. This unchanging message is revealed in Surat ash-Shu'ara':
Noah's people denied the messengers. When their brother Noah said to them: "Will you not guard against evil? I am a faithful messenger to you, so have respect and fear of Allah, and obey me. I do not ask you for any wage for it. My wage is the responsibility of the Lord of all the worlds." (Surat ash-Shu'ara', 105-109)
The 'Ad people denied the messengers when their brother Hud said to them: "Will you not guard against evil? I am a faithful messenger to you, so have respect and fear of Allah, and obey me. I do not ask you for any wage for it. My wage is the responsibility of the Lord of all the worlds." (Surat ash-Shu'ara', 123-127)
The Thamud people denied the messengers, when their brother Saleh said to them: "Will you not guard against evil? I am a faithful messenger to you, so have respect and fear of Allah, and obey me. I do not ask you for any wage for it. My wage is the responsibility of the Lord of all the worlds." (Surat ash-Shu'ara', 141-145)
Lot's people denied the messengers, when their brother Lot said to them: "Will you not guard against evil? I am a faithful messenger to you. So have respect and fear of Allah, and obey me. I do not ask you for any wage for it. My wage is the responsibility of the Lord of all the worlds." (Surat ash-Shu'ara', 160-164)
The Companions of the Thicket denied the messengers, when Jethro said to them: "Will you not guard against evil? I am a faithful messenger to you. So have respect and fear of Allah, and obey me. I do not ask you for any wage for it. My wage is the responsibility of the Lord of all the worlds." (Surat ash-Shu'ara', 176-180)
All other examples of the messages and language of the Messengers found in the Qur'an are similar. Allah reveals in other verses that the Prophet Jesus (as) and the Prophet Aaron (as) said this to their peoples:
When Jesus came with the clear signs, he said: "I have come to you with Wisdom and to clarify for you some of the things about which you have differed. Therefore, have respect and fear of Allah, and obey me. Allah is my Lord and your Lord, so worship Him. This is a straight path." (Zuhruf Suresi, 63-64)
Andolsun, Harun bundan önce onlara: 'Ey kavmim, gerçekten siz bununla fitneye düşürüldünüz (denendiniz). Sizin asıl Rabbiniz Rahman (olan Allah)dır; şu halde bana uyun ve emrime itaat edin' demişti. (Surah Ta Ha, 90)
One of the verses of the Qur'an in which believers are commanded to obey the Prophet Muhammad (saas) reads:
Say: "Obey Allah and the Messenger (Muhammad). Then if they turn away, he is only responsible for what he is charged with, and you are responsible for what you are charged with. If you obey him, you will be guided. The Messenger is only responsible for the [message's] clear transmission." . (Surat an-Nur, 54)
As we can see, all of Allah's Messengers invite their people to have faith in Allah and serve Him. They warn them about the hereafter, inform them that this world is transient, and that they will be rewarded in the hereafter for what they did here. In addition, they ask for the people's obedience. For this is Allah's commandment revealed in the Qur'an: "If you obey him, you will be guided" (Surat an-Nur, 54). They make this request because only His Messengers can lead their people to the truth by calling upon them to live according to Allah's religion.
But the Messenger's leading opponents do not accept this, because the majority of the elite have made everyone dependent on them and their material wealth. However, the Messengers proclaim that there is no other Deity and "Lord" (teacher, guide, and judge) besides Allah, and that He has commanded everyone to obey them. When the people accept this, they become believers in Allah and abandon whatever else they had been worshipping. As this signifies the end of the leaders' power and authority, they become the Messengers' greatest opponents. Another reason why the people in question react against Messengers is that according to their own foolishness and inappropriate criteria they are jealous of these holy individuals who are so valuable and superior in the Sight of Allah.
