At-Talaq 65:3

وَيَرْزُقْهُ مِنْ حَيْثُ لَا يَحْتَسِبُ ۚ وَمَن يَتَوَكَّلْ عَلَى ٱللَّهِ فَهُوَ حَسْبُهُۥٓ ۚ إِنَّ ٱللَّهَ بَٰلِغُ أَمْرِهِۦ ۚ قَدْ جَعَلَ ٱللَّهُ لِكُلِّ شَىْءٍۢ قَدْرًۭا

And He provides for him from (sources) he never could imagine. And if any one puts his trust in Allah, sufficient is (Allah) for him. For Allah will surely accomplish his purpose: verily, for all things has Allah appointed a due proportion.
