قال الشيخ رحمه الله:) ويفسد الصيام الاكل متعمدا وكذلك الشرب والجماع والارتماس في الماء والكذب على الله وعلى رسوله والائمة عليهم السلام فهذا مما يفسد الصيام ويجب على فاعلها القضاء والكفارة، ويفسده ايضا الحقنة والسعوط وازدراد الشئ كالقطعة من الحصاة والخرزة متعمدا ويجب القضاء والكفارة(.
The Shaykh (Al-Mufid), may Allah (swt) have mercy on him, said: “Eating deliberately invalidates the fast, and likewise drinking, sexual intercourse, immersion in water (al-irtimas), and lying against Allah (swt), His Messenger (saws), and the Imams (a.s), peace be upon them. This is among that which invalidates the fast, and upon the one who does them, making it up and expiation (kaffarah) are obligatory. It (fasting) is also invalidated by an enema (al-huqnah), nasal medicine (al-saut), and deliberately swallowing a thing, such as a piece of pebble or a bead, and making it up and expiation are obligatory.”
