"The Prophet ﷺ was asked about eating a mastigure and he said: 'I do not eat it, and I do not prohibit eating it.'" [He said:] There are narrations on this topic from 'Umar, Abu Sa'eed, Ibn 'Abbas, Thabit bin Wadi'ah, Jabir, and 'Abdur-Rahman bin Hasanah.  

أَنَّ النَّبِيَّ ﷺ سُئِلَ عَنْ أَكْلِ الضَّبِّ فَقَالَ لاَ آكُلُهُ وَلاَ أُحَرِّمُهُ قَالَ وَفِي الْبَابِ عَنْ عُمَرَ وَأَبِي سَعِيدٍ وَابْنِ عَبَّاسٍ وَثَابِتِ بْنِ وَدِيعَةَ وَجَابِرٍ وَعَبْدِ الرَّحْمَنِ ابْنِ حَسَنَةَ
