Hadith.4539 - Al-Qasim ibn Yahya narrated from his grandfather Al-Hasan ibn Rashid, from Yaqub al-Jufi, who said: I heard Abu al-Hasan (as) say: "There is no harm in practicing withdrawal (coitus interruptus) in six cases; the woman who is certain that she cannot conceive, the elderly woman, the ill-mannered woman, the obscene woman, the woman who does not nurse her child, and the bondwoman."
