The Prophet ﷺ said, "The most beloved names to Allah are Abdullah and Abdul-Rahman."
حدثنا أبو بكر حدثنا خالد بن مخلد حدثنا العمري عن نافع
عن النبي ﷺ قال أحب الأسماء إلى الله عز وجل عبد الله وعبد الرحمن
Muslim narrated it in the Book of Manners, Chapter on the Prohibition of Adopting the Kunyah Abu Qasim and Explanation of the Recommended Names, Hadith: 2132, from the hadith of Umari, with the same wording, and his brother Ubaydullah followed him in narrating it, as recorded there.
