Allah mentions the rebellion, defiance and stubbornness of Hud's people, and their opposition to him (peace be upon him)
﴿ قَالُوٓاْ أَجِئۡتَنَا لِنَعۡبُدَ ٱللَّهَ وَحۡدَهُ ۥ ﴾
(They said: "You have come to us that we should worship Allah Alone'') Later on, the disbelievers of Quraysh said,
﴿ وَإِذۡ قَالُواْ ٱللَّهُمَّ إِن كَانَ هَـٰذَا هُوَ ٱلۡحَقَّ مِنۡ عِندِكَ فَأَمۡطِرۡ عَلَيۡنَا حِجَارَةً۬ مِّنَ ٱلسَّمَآءِ أَوِ ٱئۡتِنَا بِعَذَابٍ أَلِيمٍ۬ ﴾
(And (remember) when they said: "O Allah! If this (the Qur'an) is indeed the truth (revealed) from You, then rain down stones on us from the sky or bring on us a painful torment.'') Muhammad bin Ishaq said that the people of Hud used to worship several idols, such as Suda', Samud and Al-Haba'. This is why Hud, peace be upon him, said to them,
﴿ قَدۡ وَقَعَ عَلَيۡڪُم مِّن رَّبِّكُمۡ رِجۡسٌ۬ وَغَضَبٌۖ ﴾
("Rijs and wrath have already fallen on you from your Lord.'') you deserve `Rijs' from your Lord because of what you said. Ibn `Abbas said that, `Rijs', means scorn and anger.
﴿ أَتُجَـٰدِلُونَنِى فِىٓ أَسۡمَآءٍ۬ سَمَّيۡتُمُوهَآ أَنتُمۡ وَءَابَآؤُكُم ﴾
("Dispute you with me over names which you have named -- you and your fathers'') (7:71). Hud said, do you dispute with me over these idols that you and your fathers made gods, even though they do not bring harm or benefit; did Allah give you authority or proof allowing you to worship them Hud further said,
﴿ مَّا نَزَّلَ ٱللَّهُ بِہَا مِن سُلۡطَـٰنٍ۬ۚ فَٱنتَظِرُوٓاْ إِنِّى مَعَڪُم مِّنَ ٱلۡمُنتَظِرِينَ ﴾
("with no authority from Allah Then wait, I am with you among those who wait.'') this is a threat and warning from the Messenger to his people.
