Warabbuka alghaniyyu thoo arrahmati in yasha' yuthhibkum wayastakhlif min baAAdikum ma yashao (surah Anam: 133)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(6:133) Your Lord is Self-Sufficient, full of compassion. *101 If He wills, He can put you away and cause whomever He wills to succeed you just as He has produced you from the seed of another people.

Wa Rabbukal ghaniyyu zur rahmah; iny yashaaa yuz hibkum wa yastakhlif mim ba`dikum wa yastakhlif mim ba`dikum maa yashaaa`u kamaaa ansha akum min zurriyyati qawmin aakhareen

*101). The Qur'anic statement: 'Your Lord is Self-Sufficient' signifies that God is in need of nothing from anyone, that none of His interests will be jeopardized by disobedience to Him, and that no benefit will accrue to Him from obedience. Even if all human beings became disobedient, God's dominion will not shrink. Nor will His dominion expand if everybody were to become obedient and serve and worship Him as they ought to. God is dependent neither upon their show of veneration nor upon their offerings. He lavishes His limitless treasures on human beings and seeks nothing in return.
The other statement, namely that 'Your Lord is full of compassion', has been made here to emphasize two things. First, that when God urges human beings to follow the Right Way, and asks them not to do anything in conflict with Ultimate Reality, He does not do so because their good behaviour benefits Him or their misconduct harms Him. He does so because good conduct is beneficial to man himself, as evil conduct is harmful to him. Hence it is out of sheer benevolence that God urges man to develop righteous conduct, for it will raise him to great heights, and He urges him to avoid evil conduct because it will lead to his own degradation. Second, that God is not unduly stern in judging man. He gets no pleasure from punishing people. He is not on the look-out for slight lapses for which to convict and persecute people. God is highly compassionate towards all His creatures and governs with utmost mercy and benevolence, and the same characterizes His dealings with human beings as well. Hence, He constantly forgives the sins of people. Many disobey, indulge in sins, commit crimes, disregard God's commands, even though they are nourished by the sustenance He provides. God, nevertheless, continually treats them with forbearance and forgives them. Again and again, He grants them respite in order that they may take heed, understand things properly and reform themselves. Had He been excessively stern, He could even have obliterated them instantly and raised up another people. He could have put an end to humanity and brought into being an altogether different species of creation.
