monotheism and Tawhid

فَلَمَّا رَءَا ٱلْقَمَرَ بَازِغًا قَالَ هَـٰذَا رَبِّى ۖ فَلَمَّآ أَفَلَ قَالَ لَئِن لَّمْ يَهْدِنِى رَبِّى لَأَكُونَنَّ مِنَ ٱلْقَوْمِ ٱلضَّآلِّينَ

And when he saw the moon rising, he said, "This is my lord." But when it set, he said, "Unless my Lord guides me, I will surely be among the people gone astray."

وَإِذَا مَسَّكُمُ ٱلضُّرُّ فِى ٱلْبَحْرِ ضَلَّ مَن تَدْعُونَ إِلَّآ إِيَّاهُ ۖ فَلَمَّا نَجَّىٰكُمْ إِلَى ٱلْبَرِّ أَعْرَضْتُمْ ۚ وَكَانَ ٱلْإِنسَـٰنُ كَفُورًا

And when adversity touches you at sea, lost are [all] those you invoke except for Him. But when He delivers you to the land, you turn away [from Him]. And ever is man ungrateful.

إِذْ قَالَ لِأَبِيهِ وَقَوْمِهِۦ مَا تَعْبُدُونَ

When he said to his father and his people, "What do you worship?"

وَٱلَّذِى هُوَ يُطْعِمُنِى وَيَسْقِينِ

And it is He who feeds me and gives me drink.
