Mishkat al-Masabih, 1811

Samura b. Jundub said God’s messenger used to order them to deduct the <i>sadaqa</i> from what they prepared for trade. Abu Dawud transmitted it.

وَعَنْ سَمُرَةَ بْنِ جُنْدُبٍ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَأْمُرُنَا أَنْ نُخْرِجَ الصَّدَقَةَ مِنَ الَّذِي نُعِدُّ لِلْبَيْعِ. رَوَاهُ أَبُو دَاوُد
