Al-Ahzab 33:38

مَّا كَانَ عَلَى ٱلنَّبِىِّ مِنْ حَرَجٍۢ فِيمَا فَرَضَ ٱللَّهُ لَهُۥ ۖ سُنَّةَ ٱللَّهِ فِى ٱلَّذِينَ خَلَوْا۟ مِن قَبْلُ ۚ وَكَانَ أَمْرُ ٱللَّهِ قَدَرًۭا مَّقْدُورًا

There can be no difficulty to the Prophet in what Allah has indicated to him as a duty. It was the practice (approved) of Allah amongst those of old that have passed away. And the command of Allah is a decree determined.
