Tafsir Ibn Kathir -> Surah Al-Fajr -> The Lord is Ever Watchful

Concerning Allah's statement,

﴿إِنَّ رَبَّكَ لَبِالْمِرْصَادِ ﴾

(Verily, your Lord is Ever Watchful.) Ibn `Abbas said, "He hears and He sees.'' This means that He watches over His creation in that which they do, and He will reward them in this life and in the Hereafter based upon what each of them strove for. He will bring all of the creation before Him and He will judge them with justice. He will requit each of them with that which he deserves, for He is far removed from injustice and tyranny.

﴿فَأَمَّا الإِنسَـنُ إِذَا مَا ابْتَلـهُ رَبُّهُ فَأَكْرَمَهُ وَنَعَّمَهُ فَيَقُولُ رَبِّى أَكْرَمَنِ - وَأَمَّآ إِذَا مَا ابْتَلَـهُ فَقَدَرَ عَلَيْهِ رِزْقَهُ فَيَقُولُ رَبِّى أَهَانَنِ - كَلاَّ بَل لاَّ تُكْرِمُونَ الْيَتِيمَ - وَلاَ تَحَاضُّونَ عَلَى طَعَامِ الْمِسْكِينِ - وَتَأْكُلُونَ التُّرَاثَ أَكْلاً لَّمّاً - وَتُحِبُّونَ الْمَالَ حُبّاً جَمّاً ﴾

(15. As for man, when his Lord tries him by giving him honor and bounties, then he says: "My Lord has honored me.'') (16. But when He tries him by straitening his means of life, he says: "My Lord has humiliated me!'') (17. But no! But you treat not the orphans with kindness and generosity!) (18. And urge not one another on the feeding of the Miskin!) (19. And you devour the Turath -- devouring with greed.) (20. And you love wealth with love Jamma.)
