Al-Ma'idah' - 5:103

مَا جَعَلَ اللّهُ مِن بَحِيرَةٍ وَلاَ سَآئِبَةٍ وَلاَ وَصِيلَةٍ وَلاَ حَامٍ وَلَـكِنَّ الَّذِينَ كَفَرُواْ يَفْتَرُونَ عَلَى اللّهِ الْكَذِبَ وَأَكْثَرُهُمْ لاَ يَعْقِلُونَ
[5:103]
Allah has not ordained (the making of) a bahirah or a saibah or a wasilah or a hami but those who disbelieve fabricate a lie against Allah, and most of them do not understand.
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: It is blasphemers who invent a lie against Allah; but most of them lack wisdom.
Allah hath not appointed anything in the nature of a Bahirah or a Sa'ibah or a Wasilah or a Hami, but those who disbelieve invent a lie against Allah. Most of them have no sense.
