﴿ وَيَٰقَوْمِ هَٰذِهِۦ نَاقَةُ ٱللَّهِ لَكُمْ ءَايَةًۭ فَذَرُوهَا تَأْكُلْ فِىٓ أَرْضِ ٱللَّهِ وَلَا تَمَسُّوهَا بِسُوٓءٍۢ فَيَأْخُذَكُمْ عَذَابٌۭ قَرِيبٌۭ ﴾

“And [then he said]: "O my people! This she-camel belonging to God shall be a token for you: so leave her alone to pasture on God's earth, and do her no harm, lest speedy chastisement befall you!"”

As part of this event, the people of Sayyidna Salih (علیہ السلام) have been reported to have said to him: قَدْ كُنتَ فِينَا مَرْ‌جُوًّا قَبْلَ هَـٰذَا ( O Salih, we had hopes in you before this - 62). It means that, before he claimed to be a prophet and started telling them to shun idol-worship, they had great hopes in him. They thought he would rise to be a great reformer and leader of their people. The reason is that Allah Ta` a1a nurtures and grooms his prophets from their childhood in a way that they become models of good morals and habits. Whoever looks at them, loves and respects them. This is what happened in the case of the Last Prophet ﷺ Before he declared that he has been sent as a prophet, the whole Arabia called him al-amin (the trustworthy one) and took him to be true and righteous. It was only when he announced his prophet-hood and prohibited idol-worship that everyone turned hostile to him.
