Do not buy fruit until its good condition becomes clear, and (the danger) of blight is no more. He said: Its good condition becoming clear implies that it becomes red or yellow.  

مسلم:١٥٣٤cحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ حَدَّثَنَا جَرِيرٌ عَنْ يَحْيَى بْنِ سَعِيدٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَبْتَاعُوا الثَّمَرَ حَتَّى يَبْدُوَ صَلاَحُهُ وَتَذْهَبَ عَنْهُ الآفَةُ قَالَ يَبْدُوَ صَلاَحُهُ حُمْرَتُهُ وَصُفْرَتُهُ
