وَلَقَدْ آتَيْنَا مُوسَى الْكِتَابَ وَقَفَّيْنَا مِن بَعْدِهِ بِالرُّسُلِ ۖ وَآتَيْنَا عِيسَى ابْنَ مَرْيَمَ الْبَيِّنَاتِ وَأَيَّدْنَاهُ بِرُوحِ الْقُدُسِ ۗ أَفَكُلَّمَا جَاءَكُمْ رَسُولٌ بِمَا لَا تَهْوَىٰ أَنفُسُكُمُ اسْتَكْبَرْتُمْ فَفَرِيقًا كَذَّبْتُمْ وَفَرِيقًا تَقْتُلُونَ (87)
(2:87) And We gave Moses the Book and sent after him a train of Messengers in succession. Then We sent Jesus, son of Mary, with clear Signs and supported him with the Holy Spirit. *93 Then how is it that whenever a Messenger came to you wish that which did not suit your lusts, you grew rebellious against him, and repudiated some and slew others.
*93). The 'spirit of holiness' signifies the knowledge derived through revelation. It also signifies the angel Gabriel who brought this revelation. It also denotes the holy spirit of Jesus, the spirit which God had endowed with angelic character.
The expression 'clear proofs' refers to those signs which are likely to convince a truth-seeking and truth-loving person that Jesus is a Prophet of God.
