I say, and with God's guidance: Everything that comes out of the two passages is considered to nullify the ablution, whether it is habitual: like urine, or non-habitual: like gas, and the worm that comes out from the front and the back; due to His saying, Glory be to Him: {Or has one of you come from the place of relieving himself} (An-Nisa: 43), and the place of relieving oneself is the name for the stable area of the earth, which is borrowed for what is expelled to it, thus encompassing both habitual and non-habitual. It is not a condition for it to flow as in what comes out from other than the two passages; because whenever it appears, it is considered to be expelled, and Allah knows best.
