At-Taubah - 9:59

وَلَوْ أَنَّهُمْ رَضُوْاْ مَا آتَاهُمُ اللّهُ وَرَسُولُهُ وَقَالُواْ حَسْبُنَا اللّهُ سَيُؤْتِينَا اللّهُ مِن فَضْلِهِ وَرَسُولُهُ إِنَّا إِلَى اللّهِ رَاغِبُونَ
[9:59]
And if they were content with what Allah and His Messenger gave them, and had said: Allah is sufficient for us; Allah will soon give us (more) out of His grace and His Messenger too; surely to Allah do we make our petition.
If only they had been content with what Allah and His Messenger gave them, and had said, "Sufficient unto us is Allah! Allah and His Messenger will soon give us of His bounty: to Allah do we turn our hopes!" (that would have been the right course).
(How much more seemly) had they been content with that which Allah and His messenger had given them and had said: Allah sufficeth us. Allah will give us of His bounty, and (also) His messenger. Unto Allah we are suppliants.
