«الأصابع سواء والأسنان سواء الثنية والضرس سواء هذه وهذه سواء» - يعني الإبهام والخنصر -
The Prophet (peace and blessings be upon him) said:
"The fingers are equal and the teeth are equal too; the front tooth and the molar are equal; this and this are equal." (The narrator says that this refers to the thumb and the little finger.)
