Ubayd bin Rifa'ah narrates this statement of his father: In the blessed time of the Prophet (peace and blessings be upon him) we used to do this: when we did not ejaculate, we did not take a ritual bath (ghusl).
Al-Bazzar, and al-Tabarani in al-Mu'jam al-Kabir, recorded it; its narrators are the narrators of the "Sahih", except for Ibn Ishaq, who is thiqah (trustworthy) but practises tadlis (concealing defects in the chain).
