[Machine] We used to compete with each other in giving charity. One of us would bring a small amount, while another man would bring half a saa. Then, some hypocrites would mock us. So, the verse (Those who defame the voluntary givers among the believers in the charities) was revealed.
كُنَّا نَتَحَامَلُ فَيَجِيءُ أَحَدُنَا بِالصَّدَقَةِ الْقَلِيلَةِ وَيَجِيءُ الرَّجُلُ بِالنِّصْفِ صَاعٍ فَيَلْمِزُنَا نَاسٌ مِنَ الْمُنَافِقِينَ فَنَزَلَتْ {الَّذِينَ يَلْمِزُونَ الْمُطَّوِّعِينَ مِنَ الْمُؤْمِنِينَ فِي الصَّدَقَاتِ} الْآيَةَ
