3. Al-Husayn ibn Muhammad has narrated from Mu’alla’ ibn Muhammad from al-Hassan ibn al-Washsha’ who has said the following: “I once asked al-Rida’ , ‘Is buying dates permissible when they are formed?’ He (the Imam) replied, ‘It is permissible when they Yazhu.’ I then asked, ‘What is Yazhu?’ He (the Imam) replied, ‘It is when they turn red, yellow and so on.’”
