Mishkat al-Masabih 6 Zakat كتاب الزكاة 35

وَعَنْ عَائِشَةَ قَالَتْ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يبْعَث عبد الله ابْن رَوَاحَةَ إِلَى يَهُودٍ فَيَخْرُصُ النَّخْلَ حِينَ يَطِيبُ قَبْلَ أَنْ يُؤْكَلَ مِنْهُ. رَوَاهُ أَبُو دَاوُدَ

‘A’isha said the Prophet used to send ‘Abdallah b. Rawaha to Jews, and he would make an estimate of the palm trees when the fruit was in good condition before any of it was eaten. Abu Dawud transmitted it.
