حد ثنا سفيان حد عن عبد الله بن دينار, عن ابن عمر(رضي الله عنهما)
سىئل النبي(صلى الله عليه و سلم) عن الضب؟ فقال:لا ا كله و لا أ حرمه
Sufyaan (ibn 'uyaynah) narrated to us from 'Abdullah ibn Deenaar from Abdullah ibn 'Umar (radhiAllahu 'anhumma) who said, "The Prophet (allayhis salat wassallam) was asked about the (ruling on eating) the dhabb4, and he replied, 'I neither eat it, nor forbid it.'"
(Musnad Ahmad, Vol. 2, p.9. The isnaad of this hadeeth is saheeh according to the conditions set by al-Bukhaaree and Muslim)
4) Dhabb is a large spine-tailed (Uromastix spinipes) found in Egypt, Arabia and Palestine. The Prophet (allayhis salat wassallam) disliked eating it even though many Arabs used to eat it but, he did not like eating it for mere personal reasons.
