Surah At-Taubah Ayah 88

But the Messenger and those who believed with him strove hard and fought with their wealth and their lives. Such are they for whom are the good things, and it is they who will be successful (88)For them Allah has prepared Gardens (Paradise) under which rivers flow, to dwell therein forever. That is the supreme success (89)

After Allah mentioned the sins of the hypocrites, He praised the faithful believers and described their reward in the Hereafter,

لَٰكِنِ الرَّسُولُ وَالَّذِينَ آمَنُوا مَعَهُ جَاهَدُوا

(But the Messenger and those who believed with him strove hard and fought) until the end of these two Ayat [9:88-89]. This describes the qualities, as well as, the reward of faithful believers. Allah said,

وَأُولَٰئِكَ لَهُمُ الْخَيْرَاتُ

(Such are they for whom are the good things), in the Hereafter, in the gardens of Al-Firdaws and the high grades.
