لَوْ أَنَّكُمْ تَتَوَكَّلُونَ عَلَى اللَّهِ حَقَّ تَوَكُّلِهِ لَرَزَقَكُمْ كَمَا يَرْزُقُ الطَّيْرَ تَغْدُو خِمَاصًا وَتَرُوحُ بِطَانًا

The Messenger of Allah (ﷺ) said: 'If you were to rely upon Allah with the reliance He is due, you would be given provision like the birds: they go out hungry in the morning and return full in the evening.'
