Obligatory Charity Tax (Zakat)
24/20. Chapter:
Whoever loves to give something in charity on the very day (he receives his earnings)
Sahih Bukhari
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 ".
Narrated `Uqba bin Al-Harith: 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 . "
