3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from ibn Bukayr who has said the following: “I once asked abu ‘Abd Allah , about a man who experiences sexual relation (because of which Ghusl (bath) is obligatory); then goes to sleep until the morning, if he can fast that day an optional fast. He (the Imam) said, ‘Up till midday it is up to his choosing.’ I then asked about a man who experiences wet dream during the day in the month of Ramadan; if he completes his fast as it is. He (the Imam) said, ‘It (completing) is not harmful.’”
