What is the ruling on a fasting person engaging in sexual intercourse without ejaculation? Does it invalidate the fast and require expiation?

Intentional sexual intercourse during the daytime in Ramadan invalidates the fast and necessitates expiation, even if ejaculation does not occur. Jurists have agreed that intentionally inserting the glans into either of the two orifices while fasting in Ramadan spoils the fast and requires making up the missed day (qada') and expiation (kaffarah), because the fulfillment of desire is achieved without ejaculation.
