It was narrated that Ibn ‘Abbas said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم forbade Ad-Dubba’, Al Hantam, Al-Muzaffat, and An NaqIr, and that Al-Busr be mixed with dried dates, and that raisins be mixed with dried dates, and he wrote to the people of Hajar saying: ‘Do not mix raisins and dried dates together.” (Sahih)
