مَا جَعَلَ اللَّهُ مِنْ بَحِيرَةٍ وَلا سَائِبَةٍ وَلا وَصِيلَةٍ وَلا حَامٍ
“It was not Allah who instituted (superstitions like those of) a slit-ear she-camel or a she-camel let loose for free pasture or idol sacrifices for twin-births in animals or stallion-camels freed from work.”
This ayah (Q5:103) lists the exact superstitious practices -- the slit-ear camel, the baheera, sa'iba, waseela, hami -- that classical sources (e.g. Sahih Muslim's hadith on Amr ibn Luhay) attribute to this same man introducing them to Arabia.
