Samurah bin Jundub (RAA) narrated that The Messenger of Allah (ﷺ) used to command us to pay Zakah from (the goods) we had prepared for sale. Related by Abu Dawud with a weak chain of narrators.

وَعَنْ سَمُرَةَ بْنِ جُنْدُبٍ ‏- رضى الله عنه ‏- قَالَ: { كَانَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-يَأْمُرُنَا; أَنْ نُخْرِجَ اَلصَّدَقَةَ مِنَ اَلَّذِي نَعُدُّهُ لِلْبَيْعِ.‏ } رَوَاهُ أَبُو دَاوُدَ, وَإِسْنَادُهُ لَيِّن ٌ [1]‏ .‏
