وَاصْبِرْ فَإِنَّ اللّهَ لاَ يُضِيعُ أَجْرَ الْمُحْسِنِينَ
[11:115]
And be patient, for surely Allah does not waste the reward of the good-doers.
And be steadfast in patience; for verily Allah will not suffer the reward of the righteous to perish.
And have patience, (O Muhammad), for lo! Allah loseth not the wages of the good.
