Hypocrisy and inconsistency

أَلَمْ تَرَ إِلَى ٱلْمَلَإِ مِنۢ بَنِىٓ إِسْرَٰٓءِيلَ مِنۢ بَعْدِ مُوسَىٰٓ إِذْ قَالُوا۟ لِنَبِىٍّ لَّهُمُ ٱبْعَثْ لَنَا مَلِكًا نُّقَـٰتِلْ فِى سَبِيلِ ٱللَّهِ ۖ قَالَ هَلْ عَسَيْتُمْ إِن كُتِبَ عَلَيْكُمُ ٱلْقِتَالُ أَلَّا تُقَـٰتِلُوا۟ ۖ قَالُوا۟ وَمَا لَنَآ أَلَّا نُقَـٰتِلَ فِى سَبِيلِ ٱللَّهِ وَقَدْ أُخْرِجْنَا مِن دِيَـٰرِنَا وَأَبْنَآئِنَا ۖ فَلَمَّا كُتِبَ عَلَيْهِمُ ٱلْقِتَالُ تَوَلَّوْا۟ إِلَّا قَلِيلًا مِّنْهُمْ ۗ وَٱللَّهُ عَلِيمٌۢ بِٱلظَّـٰلِمِينَ

Have you not considered the assembly of the Children of Israel after [the time of] Moses when they said to a prophet of theirs, "Send to us a king, and we will fight in the way of Allāh"? He said, "Would you perhaps refrain from fighting if battle was prescribed for you?" They said, "And why should we not fight in the cause of Allāh when we have been driven out from our homes and from our children?" But when battle was prescribed for them, they turned away, except for a few of them. And Allāh is Knowing of the wrongdoers.

ثُمَّ إِذَا كَشَفَ ٱلضُّرَّ عَنكُمْ إِذَا فَرِيقٌ مِّنكُم بِرَبِّهِمْ يُشْرِكُونَ

Then when He removes the adversity from you, at once a party of you associates others with their Lord

وَأَنَّهُمْ يَقُولُونَ مَا لَا يَفْعَلُونَ

And that they say what they do not do? -

فَإِذَا رَكِبُوا۟ فِى ٱلْفُلْكِ دَعَوُا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ فَلَمَّا نَجَّىٰهُمْ إِلَى ٱلْبَرِّ إِذَا هُمْ يُشْرِكُونَ

And when they board a ship, they supplicate Allāh, sincere to Him in religion [i.e., faith and hope]. But when He delivers them to the land, at once they associate others with Him
