حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا سُفْيَانُ عَنِ ابْنِ أَبِي لَيْلَى عَنِ الْعَوْفِيِّ عَنِ ابْنِ عُمَرَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا تَتَبَايَعُوا الثَّمَرَةَ حَتَّى يَبْدُوَ صَلَاحُهَا قَالَ وَمَا بُدُوُّ صَلَاحِهَا قَالَ تَذْهَبُ عَاهَتُهَا وَيَخْلُصُ طَيِّبُهَا
مسند امام احمد بن حنبل · Hadith 5521
It was narrated that Ibn Umar said: The Messenger of Allah (PBUH) said: "Do not buy or sell crops until they become sound (ripe)." It was said: What does becoming sound mean? He said: "When danger of blight has passed and the crop has reached the best stage."
