Sahih al-Bukhari · Book 24: Obligatory Charity Tax (Zakat) · Whoever loves to give something in charity on the very day (he receives his earnings)
Narrated `Uqba bin Al-Harith:
حَدَّثَنَا أَبُو عَاصِمٍ ، عَنْ عُمَرَ بْنِ سَعِيدٍ ، عَنِ ابْنِ أَبِي مُلَيْكَةَ ، أَنَّ عُقْبَةَ بْنَ الْحَارِثِ ـ رضى الله عنه ـ حَدَّثَهُ قَالَ صَلَّى بِنَا النَّبِيُّ صلى الله عليه وسلم الْعَصْرَ، فَأَسْرَعَ ثُمَّ دَخَلَ الْبَيْتَ، فَلَمْ يَلْبَثْ أَنْ خَرَجَ، فَقُلْتُ أَوْ قِيلَ لَهُ فَقَالَ " كُنْتُ خَلَّفْتُ فِي الْبَيْتِ تِبْرًا مِنَ الصَّدَقَةِ، فَكَرِهْتُ أَنْ أُبَيِّتَهُ فَقَسَمْتُهُ " .
Once the Prophet (ﷺ) offered the `Asr prayer and then hurriedly went to his house and returned immediately. I (or somebody else) asked him (as to what was the matter) and he said, "I left at home a piece of gold which was from the charity and I disliked to let it remain a night in my house, so I got it distributed . "
