Hadith on Reliance: If Muslims work for their provision like the birds do, then Allah will provide

Umar ibn Al-Khattab reported: The Messenger of Allah, peace be upon him, said, “If you were to rely upon Allah with reliance due to Him, then He would provide for you just as He provides for the birds. They go out in the morning with empty stomachs but return full.”

[Sunan At-Tirmidhi, Book of Asceticism, Number 2344, Sahih]

عَنْ عُمَرَ بْنِ الْخَطَّابِ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَوْ أَنَّكُمْ كُنْتُمْ تَوَكَّلُونَ عَلَى اللَّهِ حَقَّ تَوَكُّلِهِ لَرُزِقْتُمْ كَمَا يُرْزَقُ الطَّيْرُ تَغْدُو خِمَاصًا وَتَرُوحُ بِطَانًا

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ

سنن الترمذي كِتَاب الزُّهْدِ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَاب فِي التَّوَكُّلِ عَلَى اللَّهِ
