Muwatta Malik, Book 42, Hadith 7 (USC-MSA) ⓘ
Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn Yasar that the Messenger of Allah, may Allah bless him and grant him peace, forbade preparing nabidh from nearly ripe dates and fresh dates together, and from dates and raisins together.
وَحَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، . أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى أَنْ يُنْبَذَ الْبُسْرُ وَالرُّطَبُ جَمِيعًا وَالتَّمْرُ وَالزَّبِيبُ جَمِيعًا .
