Riyad as-Salihin

Asma' bint Abu Bakr As-Siddiq (May Allah be pleased with her) said: My mother came to me while she was still a polytheist, so I asked Messenger of Allah (ﷺ), "My mother, who is ill-disposed to Islam, has come to visit me. Shall I maintain relations with her?" He (ﷺ) replied, "Yes, maintain relations with your mother".
