قَالُوا۟ يَـٰصَـٰلِحُ قَدْ كُنتَ فِينَا مَرْجُوًّا قَبْلَ هَـٰذَآ ۖ أَتَنْهَىٰنَآ أَن نَّعْبُدَ مَا يَعْبُدُ ءَابَآؤُنَا وَإِنَّنَا لَفِى شَكٍّ مِّمَّا تَدْعُونَآ إِلَيْهِ مُرِيبٍ ٦٢
They said, "O Ṣāliḥ, you were among us a man of promise before this. Do you forbid us to worship what our fathers worshipped? And indeed we are, about that to which you invite us, in disquieting doubt."
The Conversation between Salih and the People of Thamud
Allah, the Exalted, mentions what transpired in the discussion between Salih and his people. Allah informs of their ignorance and obstinacy in their statement,
قَدْ كُنتَ فِينَا مَرْجُوًّا قَبْلَ هَـذَا
(You have been among us as a figure of good hope till this!) They were saying in this, "We had hope in your strong intellect before you began saying what you have said."
أَتَنْهَانَآ أَن نَّعْبُدَ مَا يَعْبُدُ ءابَاؤُنَا
(Do you (now) forbid us the worship of what our fathers have worshipped) "what those who were before us were upon."
وَإِنَّنَا لَفِى شَكٍّ مِّمَّا تَدْعُونَآ إِلَيْهِ مُرِيبٍ
(But we are really in grave doubt as to that which you invite us.) This alludes to the great amount of doubt that they had.
قَالَ يقَوْمِ أَرَأَيْتُمْ إِن كُنتُ عَلَى بَيِّنَةٍ مِّن رَّبِّى
(He said: "O my people! Tell me, if I have a clear proof from my Lord...") `In reference to what He (Allah) has sent me with to you, I am upon conviction and sure evidence.'
وَءَاتَـنِى مِنْهُ رَحْمَةً فَمَن يَنصُرُنِى مِنَ اللَّهِ إِنْ عَصَيْتُهُ
(and there has come to me a mercy from Him, who then can help me against Allah, if I were to disobey Him) `and abandon calling you to the truth and the worship of Allah alone. If I did so, you would not be able to bring me any benefit, nor increase me
غَيْرَ تَخْسِيرٍ
(but in loss.)' This means loss and ruin.
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.
Those who ignore God’s word, are ignored by God. This happens to a lesser degree in the present world but, on Doomsday, this will be a total reality. At that time all the arrogant and insolent people will be denied God’s grace; the grace of God will be shared only by those who lived in the world as His loyal and obedient subjects. God has introduced the principle of succession (istikhlaf) in this world, that is, the removal of a community from its position of prominence and the installing of another community in its place. This temporary prominence in the world is for the purpose of putting people to the test. In the Hereafter, in the perfect world of God, such prominence will be granted only to people of true Faith as an everlasting reward. The system of this world of trial has been formulated in such a way that, here, a man is always placed between good and bad. He has the option to follow either of these two ways. Furthermore, evil is largely dominant in this world. Only the strength of theoretical arguments is on the side of goodness. On the contrary, material power weighs in on the side of evil, and that too in such great measure that its flag-bearers develop attitudes of arrogance and hauteur and create such an atmosphere of pressure in the environment that the common man loses the courage to proceed towards the Truth.
