عَنْ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ لَوْ أَنَّكُمْ تَتَوَكَّلُونَ عَلَى اللَّهِ حَقَّ تَوَكُّلِهِ لَرَزَقَكُمْ كَمَا يَرْزُقُ الطَّيْرَ تَغْدُو خِمَاصًا وَتَرُوحُ بِطَانًا
Sayyiduna Umar bin Khattab (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: If you place your trust in Allah as it is His right to be trusted, He will provide for you as He provides for the bird, which leaves in the morning with an empty stomach and returns in the evening with a full stomach.
