Humayd ibn Ziyad has narrated from ‘Abd Allah ibn Ahmad from Ali ibn al-Hassan from Muhammad ibn Ziyad ibn ‘Isa Bayya’ al- Sabiriy from Aban ibn ‘Uthman from Ibrahim who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘If the child feels compassion toward al-Qabilah (special nurse who helps one’s mother during her giving birth and thereafter) she becomes unlawful to him for marriage as well as her children.’”
