Sayyidah Ayshah(RA)said that her paternal uncle through fosterage sought permission to meet her. She declined to allow him (admittance to her home) till she had asked Allah’s Messenger (SAW). So, Allah’s Messenger (SAW) said, “He can come to you, for, he is your paternal uncle.” She submitted, “Only a woman had suckled me’. He said (again). “He is your paternal uncle and may visit you.”
