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

The fourth verse (12) has been revealed about a particular event. What happened was that the Mushriks of Makkah placed a host of demands before the Holy Prophet One of these was, ` our idols have been maligned in this Qur'an, therefore, we cannot believe in it. So, you should either bring some other Qur'an, or improve it by making alterations in it:;i ائْتِ بِقُرْ‌آنٍ غَيْرِ‌ هَـٰذَا أَوْ بَدِّلْ (Bring a Qur'an other than this, or change it - Yunus, 10:15) '. (Al-Baghawi, Mazhari)

Another demand they came up with was, ` we are to believe in your prophesy only when some treasure, like the treasures of the kings of the world, is sent down for you and which you dole out to everyone around. Or that some angel descends from the heavens and hangs out with you everywhere testifying that you were a Messenger of Allah in all certainty.'
