The sound of winds in one’s abdomen

Question 82: If a person performs Wudoo’ (ablution) and hears his stomach rumble, but does not pass wind from his back passage, what is the ruling on this? Does he still have Wudoo’ or does this nullify it?

Answer: All praise be to Allaah Alone, and peace and blessings be upon His Messenger, and his family and Companions!

If a person has Wudoo’ and hears the sound of wind or gas inside his stomach, this does not nullify his Wudoo’ if he does not pass anything, because the Prophet (peace be upon him) said:“If any one of you feels something in his stomach, and is not sure whether something came out of him or not, he should not leave the Masjid (mosque) unless he hears a sound or detects an odor.” (Related by Muslim in his Saheeh (authentic) Book of Hadeeth)… read more here.
