After Allah mentions the extended time and respite that is allowed to those who are in misguidance, increasing them in misguidance, He informs of the increase in guidance of those who are rightly guided. Similarly He says,

[وَإِذَا مَآ أُنزِلَتْ سُورَةٌ فَمِنْهُمْ مَّن يَقُولُ أَيُّكُمْ زَادَتْهُ هَـذِهِ إِيمَـناً]

(And whenever there comes down a Surah, some of them say: "Which of you has had his faith increased by it'') [9:124] And the following Ayah also shows this. Concerning Allah's statement,

[وَالْبَـقِيَاتُ الصَّـلِحَاتُ]

(And the righteous good deeds that last) Its explanation has already preceded in Surat Al-Kahf, along with a lengthy discussion concerning it and the related Hadiths.

[خَيْرٌ عِندَ رَبِّكَ ثَوَابًا]

((they) are better with your Lord for reward.) meaning the recompense and reward.

[وَخَيْرٌ مَّرَدّاً]

(and better for resort.) meaning in the final outcome, the result for its doer.

[أَفَرَأَيْتَ الَّذِى كَفَرَ بِـَايَـتِنَا وَقَالَ لأوتَيَنَّ مَالاً وَوَلَداً - أَطَّلَعَ الْغَيْبَ أَمِ اتَّخَذَ عِندَ الرَّحْمَـنِ عَهْداً - كَلاَّ سَنَكْتُبُ مَا يَقُولُ وَنَمُدُّ لَهُ مِنَ الْعَذَابِ مَدّاً - وَنَرِثُهُ مَا يَقُولُ وَيَأْتِينَا فَرْداً ]

(77. Have you seen him who disbelieved in Our Ayat and said: "I shall certainly be given wealth and children [if I live again].'') (78. Has he known the Unseen or has he taken a covenant from the Most Gracious) (79. Nay, We shall record what he says, and We shall increase his torment;) (80. And We shall inherit from him all that he speaks of, and he shall come to Us alone.)
