Allah's support for His messenger

وَلَقَدْ نَعْلَمُ أَنَّكَ يَضِيقُ صَدْرُكَ بِمَا يَقُولُونَ

And We already know that your breast is constrained by what they say.

لِنُرِيَكَ مِنْ ءَايَـٰتِنَا ٱلْكُبْرَى

That We may show you [some] of Our greater signs.

وَأَلْقِ مَا فِى يَمِينِكَ تَلْقَفْ مَا صَنَعُوٓا۟ ۖ إِنَّمَا صَنَعُوا۟ كَيْدُ سَـٰحِرٍ ۖ وَلَا يُفْلِحُ ٱلسَّاحِرُ حَيْثُ أَتَىٰ

And throw what is in your right hand; it will swallow up what they have crafted. What they have crafted is but the trick of a magician, and the magician will not succeed wherever he is."

أَلَمْ نَشْرَحْ لَكَ صَدْرَكَ

Did We not expand for you, [O Muḥammad], your breast?
