Surat Ibrahim (7-8)

{وَإِذْ تَأَذَّنَ رَبُّكُمْ لَئِن شَكَرْتُمْ لأَزِيدَنَّكُمْ وَلَئِن كَفَرْتُمْ إِنَّ عَذَابِي لَشَدِيدٌ} (إبراهيم : 7)

7- And remember when your Lord informed you that if you show gratitude to the favors which He bestowed upon you and you face them with faith and obedience, they shall be continuous and more. However, if you show ingratitude and do not thank Me for them, the prepared torment for the disobedient is severe either by taking away favors or taking away the blessing or by punishing you.

{وَقَالَ مُوسَى إِن تَكْفُرُواْ أَنتُمْ وَمَن فِي الأَرْضِ جَمِيعاً فَإِنَّ اللّهَ لَغَنِيٌّ حَمِيدٌ} (إبراهيم : 8)

8- Moses (peace be upon him) said to his people: Allah is Self-Sufficient and is not in need to your thanking and obedience. If you and the entire people of the earth had disbelieved, He is Self-Sufficient and the dominion of heavens and the earth belongs to Him. He is not harmed by the disbelief of disbelievers which does not decrease His Dominance or add to it. He is worthy of praise due to His Consecutive Favors to His People. The reward of praise and thanking returns to you by increasing His Favors to you and reforming your conditions, and you shall have the reward on the Day of Recompense.
