قَالَتْ لَهُمْ رُسُلُهُمْ إِن نَّحْنُ إِلَّا بَشَرٌۭ مِّثْلُكُمْ وَلَٰكِنَّ ٱللَّهَ يَمُنُّ عَلَىٰ مَن يَشَآءُ مِنْ عِبَادِهِۦ ۖ وَمَا كَانَ لَنَآ أَن نَّأْتِيَكُم بِسُلْطَٰنٍ إِلَّا بِإِذْنِ ٱللَّهِ ۚ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ
Their messengers said to them, "We are only men like you, but Allah confers favor upon whom He wills of His servants. It has never been for us to bring you evidence except by permission of Allah. And upon Allah let the believers rely.
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.
