Muwatta Imam Malik Book of Sadaqa, Hadith 11

Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn Yasar that a man of the Banu Asad said, "My family and I dismounted to rest at Baqi. My family said to me, 'Go to the Messenger of Allah ﷺ and ask him for something that we can eat,' and they began to mention their need. I went to the Messenger of Allah ﷺ and found that a man was asking for something, and the Messenger of Allah ﷺ was saying, 'I do not have anything to give you.' The man turned away from him in anger, saying, 'By my life! You give to whomever you wish.' The Messenger of Allah ﷺ said, 'He is angry with me because I do not have anything to give him. Whoever asks of you while he has an uqiya or its like, has asked with importunity.' "
The man continued, "I said to myself about a camel that we had, 'It is better than an uqiya.' (Malik explained that an uqiya was forty dirhams.) So I returned and did not ask him for anything, and the Messenger of Allah ﷺ sent me barley and raisins after that. He gave us from his share until Allah, the Mighty, the Majestic gave us relief."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ رَجُلٍ، مِنْ بَنِي أَسَدٍ أَنَّهُ قَالَ نَزَلْتُ أَنَا وَأَهْلِي، بِبَقِيعِ الْغَرْقَدِ فَقَالَ لِي أَهْلِي اذْهَبْ إِلَى رَسُولِ اللَّهِ ﷺ فَاسْأَلْهُ لَنَا شَيْئًا نَأْكُلُهُ . وَجَعَلُوا يَذْكُرُونَ مِنْ حَاجَتِهِمْ . فَذَهَبْتُ إِلَى رَسُولِ اللَّهِ ﷺ فَوَجَدْتُ عِنْدَهُ رَجُلاً يَسْأَلُهُ وَرَسُولُ اللَّهِ ﷺ يَقُولُ " لاَ أَجِدُ مَا أُعْطِيكَ " . فَتَوَلَّى الرَّجُلُ عَنْهُ وَهُوَ مُغْضَبٌ وَهُوَ يَقُولُ لَعَمْرِي إِنَّكَ لَتُعْطِي مَنْ شِئْتَ . فَقَالَ رَسُولُ اللَّهِ ﷺ " إِنَّهُ لَيَغْضَبُ عَلَىَّ أَنْ لاَ أَجِدَ مَا أُعْطِيهِ مَنْ سَأَلَ مِنْكُمْ وَلَهُ أُوقِيَّةٌ أَوْ عَدْلُهَا فَقَدْ سَأَلَ إِلْحَافًا " . قَالَ الأَسَدِيُّ فَقُلْتُ لَلَقْحَةٌ لَنَا خَيْرٌ مِنْ أُوقِيَّةٍ . قَالَ مَالِكٌ وَالأُوقِيَّةُ أَرْبَعُونَ دِرْهَمًا . قَالَ فَرَجَعْتُ وَلَمْ أَسْأَلْهُ فَقُدِمَ عَلَى رَسُولِ اللَّهِ ﷺ بَعْدَ ذَلِكَ بِشَعِيرٍ وَزَبِيبٍ فَقَسَمَ لَنَا مِنْهُ حَتَّى أَغْنَانَا اللَّهُ عَزَّ وَجَلَّ .
