Masruq reported: The Christians and the people of Islam boasted to one another. Some of them said, “We are better than you!” The others said, “No, we are better than you!” Then, Allah Almighty revealed the verse, “The matter is neither by your wishes, nor those of the People of the Book! Whoever commits evil will be rewarded accordingly, and they will find no protector or helper besides Allah.” (4:123)

عَنْ مَسْرُوقٍ قَالَ تَفَاخَرَ النَّصَارَى وَأَهْلُ الإِسْلامِ فَقَالَ هَؤُلاءِ نَحْنُ أَفْضَلُ مِنْكُمْ وَقَالَ هَؤُلاءِ نَحْنُ أَفْضَلُ مِنْكُمْ فَأَنْزَلَ اللَّهُ جل ثناؤه لَّيْسَ بِأَمَانِيِّكُمْ وَلَآ أَمَانِىِّ أَهْلِ ٱلْكِتَـٰبِ مَن يَعْمَلْ سُوٓءًۭا يُجْزَ بِهِ وَلَا يَجِدْ لَهُ مِن دُونِ ٱللَّهِ وَلِيًّۭا وَلَا نَصِيرًۭا
