[Machine] "Allah, the Blessed and Exalted, said, 'And his gestation and weaning is thirty months' [Al-Ahqaf: 15]. And He said, 'And his weaning is in two years' [Luqman: 14]. And He said, 'Mothers may breastfeed their children for two complete years' [Al-Baqarah: 233]. So breastfeeding is twenty-four months and gestation is six months. Uthman commanded that it should be revoked, but it was found that it had already been abrogated, and Allah knows best."
