In the last verse here (8) , it was said: قَالَ مُوسَىٰ إِن تَكْفُرُوا أَنتُمْ وَمَن فِي الْأَرْضِ جَمِيعًا (And Musa said, "If you are ungrateful, you and all those on earth, then, Allah is free of all needs, worthy of every praise.) " This was said by Sayyidna Musa علیہ السلام to his people. He is telling them that should they or, for that matter, all inhabitants of the earth become ungrateful to Allah Ta’ ala, it is not going to cause any loss to Allah Ta’ ala. As for Him, He needs no praise or gratitude for Himself. He is Independent. He is beyond that. He is intrinsically Praised and deserving of praise. If you do not praise Him, the angels do, all of them, and so does every particle of this universe.
So, whatever good there is in gratitude, that is for you alone. There-fore, when you are asked to be grateful by Allah Ta’ ala, there is no gain for Him in doing so. In fact, it is His infinite mercy reaching out to you in your interest.
