وَإِنَّ مِنْ أَهْلِ الْكِتَابِ لَمَنْ يُؤْمِنُ بِاللَّهِ وَمَا أُنْزِلَ إِلَيْكُمْ وَمَا أُنْزِلَ إِلَيْهِمْ خَاشِعِينَ لِلَّهِ لَا يَشْتَرُونَ بِآيَاتِ اللَّهِ ثَمَنًا قَلِيلًا أُولَئِكَ لَهُمْ أَجْرُهُمْ عِنْدَ رَبِّهِمْ إِنَّ اللَّهَ سَرِيعُ الْحِسَابِ ﴿۱۹۹﴾ يَا أَيُّهَا الَّذِينَ آمَنُوا اصْبِرُوا وَصَابِرُوا وَرَابِطُوا وَاتَّقُوا اللَّهَ لَعَلَّكُمْ تُفْلِحُونَ ﴿۲۰۰﴾

﴾199﴿ Wa inna min Ahlil Kitaabi lamai yu'minu billaahi wa maaa unzila ilaikum wa maaa unzila ilaihim khaashi 'eena lillaahi laa yashtaroona bi Aayaatil laahi samanan qaleelaa; ulaaa'ika lahum ajruhum 'inda Rabbihim; innal laaha saree'ul hisaab
﴾200﴿ Yaaa aiyuhal lazeena aamanus biroo wa saabiroo wa raabitoo wattaqul laaha la'allakum tuflihoon

﴾199﴿ And indeed, among the People of the Book are some who believe in Allah and in what has been sent down to you and what was sent down to them; they are humble before Allah, and they do not sell the signs of Allah for a small price (of this world). For such people, their reward is with their Lord; indeed, Allah is swift in reckoning.
﴾200﴿ O believers! Be patient, and urge each other to patience, and prepare yourselves for struggle (jihad), and fear Allah so that you may succeed.

[199] This, after the general glad tidings, is a special glad tidings for specific people, and it describes the qualities of the true God-fearing scholars. (أَجْرُهُمْ) refers to the reward for these deeds, and it indicates the acceptance of their actions. These three qualities are the reason for the acceptance of righteous deeds.
[200] This verse is the summary of the entire surah. In (اصْبِرُوا), there is an indication of steadfastness upon the Sunnah of the Prophet (may Allah bless him and give him peace), which is the essence of Prophethood. In (صَابِرُوا), it refers to striving and jihad—one meaning is encouraging each other to be patient, and another is to overcome the enemy through perseverance. In (رَابِطُوا), it points to spending in the way of Allah—one meaning is guarding the borders of Islam. In (وَاتَّقُوا اللَّهَ), it means upholding tawheed. These are the principles of success and prosperity. Similarly, (اصْبِرُوا) refers to the first part of the surah, meaning to be patient in the face of the objections of the Christians (the misguided). (صَابِرُوا) refers to the second part, meaning to confront the wrongdoings of the People of the Book. (رَابِطُوا) refers to the third part, meaning to firmly uphold the laws of giving and invitation. (وَاتَّقُوا) pertains to the fourth part, meaning to act upon those qualities that prevent defeat and to guard oneself against the vices of the hypocrites and Jews.
