11:12
فَلَعَلَّكَ تَارِكٌۢ بَعْضَ مَا يُوحَىٰٓ إِلَيْكَ وَضَآئِقٌۢ بِهِۦ صَدْرُكَ أَن يَقُولُوا۟ لَوْلَآ أُنزِلَ عَلَيْهِ كَنزٌ أَوْ جَآءَ مَعَهُۥ مَلَكٌ ۚ إِنَّمَآ أَنتَ نَذِيرٌۭ ۚ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ وَكِيلٌ
Then would you possibly leave [out] some of what is revealed to you, or is your breast constrained by it because they say, "Why has there not been sent down to him a treasure or come with him an angel?" But you are only a warner. And Allah is Disposer of all things.

Tafsir
Ibn Kathīr (abridged)
The Messenger grieving by the Statements of the Polytheists, and His Gratification
This statement of Allah, the Exalted, to His Messenger comforted the worries that the polytheists were causing him due to their statements directed towards him. This is just as Allah says about them,
وَقَالُواْ مَا لِهَـذَا الرَّسُولِ يَأْكُلُ الطَّعَامَ وَيَمْشِى فِى الاٌّسْوَاقِ لَوْلا أُنزِلَ إِلَيْهِ مَلَكٌ فَيَكُونَ مَعَهُ نَذِيراً - أَوْ يُلْقَى إِلَيْهِ كَنْزٌ أَوْ تَكُونُ لَهُ جَنَّةٌ يَأْكُلُ مِنْهَا وَقَالَ الظَّـلِمُونَ إِن تَتَّبِعُونَ إِلاَّ رَجُلاً مَّسْحُوراً
(And they say: "Why does this Messenger eat food, and walk about in the markets. Why is not an angel sent down to him to be a warner with him" Or; "(why) has not a treasure been granted to him, or why has he not a garden whereof he may eat" And the wrongdoers say: "You follow none but a man bewitched.") 25:7-8 Thus, Allah commanded His Messenger and guided him to not let these statements of theirs grieve his heart. Allah directed him to not let these statements prevent him, or deter him from calling them to Allah, both day and night. This is as Allah said,
وَلَقَدْ نَعْلَمُ أَنَّكَ يَضِيقُ صَدْرُكَ بِمَا يَقُولُونَ
(Indeed, We know that your breast is straitened at what they say.) 15:97 Allah says in this verse,
