Umar bin al Khattab heard the Messenger of Allah ﷺ say: ʿIf you were to put your trust in Allah as you should, you would be given provision like the birds: they go out hungry in the morning and come back with full bellies in the evening.” (Using translation from Aḥmad 205)
سَمِعَ نَبِيَّ اللَّهِ ﷺ يَقُولُ «لَوْ أَنَّكُمْ تَوَكَّلُونَ عَلَى اللَّهِ حَقَّ تَوَكُّلِهِ لَرَزَقَكُمْ كَمَا يَرْزُقُ الطَّيْرَ؛ تَغْدُو خِمَاصًا وَتَرُوحُ بِطَانًا»
