the Prophet (peace be upon him) said, “Verily Allah has obligated the obligations – so do not neglect them. And He has limited the limits – so do not transgress them. And His silence about things is from His mercy, not forgetfulness, so do not investigate them.” (Ad-Darqutni No. 4/199 and Al-Baihaqi No. 10/122). According to this principle, all animals are permissible until the evidence of prohibition is established.”
