The Messenger of Allah ﷺ forbade the sale of fruits until they are ripened (tushqihah). He was asked: What do you mean by their ripening (ishqah)? He replied: They become red or yellow, and they are eaten. (Using translation from Abū Dāʾūd 3370)
سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللهِ يَقُولُ نَهَى رَسُولُ اللهِ ﷺ عَنْ بَيْعِ الثَّمَرِ حَتَّى تُشَقِّحَ قُلْتُ مَتَى تُشَقِّحُ؟ قَالَ تَحْمَارُّ أَوْ تَصْفَارُّ وَيُؤْكَلُ مِنْهَا
