O Abdullah ibn Amr, what do you say? He said: It was brought to the Messenger of Allah, peace and blessings be upon him, while I was sitting, and he did not eat it, nor did he forbid eating it, and he claimed that it menstruates.(1)

27 - Chapter on Eating the Dabb (Desert Lizard)

3793 - Hafs ibn Umar narrated to us, Shu'bah narrated to us, from Abu Bishr, from Sa'id ibn Jubayr, from Ibn Abbas: that his maternal aunt gifted to the Messenger of Allah, peace and blessings be upon him, clarified butter, dabb (desert lizards), and dried yogurt (aqit). He ate from the clarified butter and the dried yogurt, but left the dabb out of distaste. Yet it was eaten at his table, and had it been forbidden, it would not have been eaten at the table of the Messenger of Allah, peace and blessings be upon him.(2)

3794 - Al-Qa'nabi narrated to us, from Malik, from Ibn Shihab, from Abu Umamah ibn Sahl ibn Hunayf, from Abdullah ibn Abbas--------------------------------------------

(1) Its chain is weak due to the unknown status of Muhammad ibn Khalid ibn al-Huwayrith and his father.
Al-Bayhaqi also recorded it in 9/321 via Abu Dawud, with this chain.
On this topic, there is also a hadith from Khuzaymah ibn Jaz' recorded by Ibn Majah (3245). Al-Hafiz declared its chain weak in "Al-Fath" 9/662.

(2) Its chain is authentic. Abu Bishr: he is Ja'far ibn Iyas, Abu Wahshiyyah.
Al-Bukhari also recorded it (2575), Muslim (1947), and Al-Nasa'i (4318) via Shu'bah, with this chain.
It is also in "Musnad Ahmad" (2299), and "Sahih Ibn Hibban" (5221) and (5223). See what follows it, and what preceded it under number 3730.
Al-Khattabi said: People have differed regarding eating the dabb. A group of scholars permitted it; this was narrated from Umar ibn al-Khattab, may Allah be pleased with him. Malik ibn Anas, al-Awza'i, and al-Shafi'i adopted this view [we say: likewise Ahmad, as in the "Masa'il" of his son Abdullah (1193), and al-Layth and Ibn al-Mundhir, as quoted by Ibn Qudamah in "Al-Mughni" 13/341]. Another group disapproved of it; this was narrated from Ali, may Allah be pleased with him, and Abu Hanifah and his companions held this view [we say: Ibn Qudamah quoted in "Al-Mughni" 13/341 that Abu Hanifah and al-Thawri said: it is forbidden].
