The Messenger of Allah ﷺ said, "The best remembrance is the quiet one, and the best provision is what suffices."
حدثنا وكيع حدثنا أسامة بن زيد عن محمد بن عبد الرحمن بن أبي لبيبة
قال رسول الله ﷺ خير الذكر الخفي وخير الرزق ما يكفي
Its isnad is daif due to its being disconnected. Usama bin Zayd is Al-Laythi. Muhammad bin Abdul-Rahman bin Abu Lubaba, we mentioned in 93 that he is trustworthy, and Bukhari gave his biography in Al-Kabir 1/152–153 without mentioning any criticism of him, but he came later, narrating from the Followers, such as Saeed bin Musayab and Umar bin Saad bin Abu Waqqas, and it is stated explicitly in Tahdheeb that his narration from Saad was disconnected.His lineage is also given as Muhammad bin Abdul-Rahman ibn Lubaba, as will come in the isnad after this one. It has been said that Lubaba was his mother, and it has been said that Abu Lubaba was his grandfather, whose name was Wardan. It appears that both statements are correct.
