Riyad as-Salihin, Book 1, Hadith 325 (In-Book) ⓘ
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, "My mother, who is ill-disposed to Islam, has come to visit me. Shall I maintain relations with her?" He replied, "Yes, maintain relations with your mother".[Al- Bukhari and Muslim].
وعن أسماء بنت أبي بكر الصديق رضي الله عنهما قالت: قدمت على أمي وهي مشركة في عهد رسول الله صلى الله عليه وسلم، فاستفتيت رسول الله صلى الله عليه وسلم قلت: قدمت علي أمي وهي راغبة، أفأصل أمي؟ قال: "نعم صلي أمك" ((متفق عليه)).
