عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ أُهْدِيَتْ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ثَلَاثُ طَوَائِرَ فَأَطْعَمَ خَادِمَهُ طَائِرًا فَلَمَّا كَانَ فِي الْغَدِ أَتَتْهُ بِهِ فَقَالَ لَهَا أَلَمْ أَنْهَكِ أَنْ تَرْفَعِي شَيْئًا فَإِنَّ اللَّهَ عَزَّ وَجَلَّ يَأْتِي بِرِزْقِ كُلِّ غَدٍ
Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that three birds were presented as a gift to the Noble Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) gave one bird to his servant to eat. The next day, the servant presented a bird before the Prophet (peace and blessings be upon him), but he said: "Did I not forbid you from keeping anything for the next day? For Allah, the Exalted, grants sustenance for every day."
