What is the ruling on one from whom semen was emitted with desire during a phone conversation with his wife in the daytime of Ramadan?

The emission of semen due to a phone call with one's wife does not invalidate the fast according to the preponderant opinion, as it is less stimulating to desire than repeated looking, which does not invalidate the fast. However, it is more cautious to make up that day to avoid the difference of opinion among the imams. One must avoid anything that arouses desire while fasting, in compliance with Allah's saying in the Hadith Qudsi: "He gives up his food, his drink, and his sexual desire for My sake."
