The wife of Uthman bin Mazun, whose name was Khawla bint Hakeem, came to visit Ayesha looking unkempt and neglected.Ayesha asked her, "What is the matter with you?"She replied, "My husband stands in prayer all night and fasts all day."Then the Prophet ﷺ came in, and Ayesha mentioned this to him. The Prophet ﷺ later met Uthman and said, "Uthman, monasticism has not been prescribed for us. Do you not have an example in me? By Allah, I am the most fearful of Allah among you and the most observant of His limits."
دخلت امرأة عثمان بن مظعون- واسمها خولة بنت حكيم- على عائشة وهي باذة الهيئة، فسألتها: ما شأنك؟ فقالت: زوجي يقوم الليل، ويصوم النهار. فدخل النبي ﷺ فذكرت ذلك له عائشة، فلقي النبي ﷺ فقال: يا عثمان إن الرهبانية لم تكتب علينا، أما لك في أسوة؟ فو الله إن أخشاكم لله، وأحفظكم لحدوده لأنا.
Abdul-Razzaq (10375) narrated it from Mamar, from Zuhri, from Urwa and Amra, from Ayesha, who said, then he mentioned it. Bazzar narrated it by this same route in Kashf Astar (1458), as did Ibn Hibban (9), but only from Urwa alone.Ahmad (25893) narrated it from Abdul-Razzaq, who said, Mamar related to us, from Zuhri, from Urwa, who said, "The wife of Uthman came in," and he mentioned it as a mursal report.Haythami pointed to this in al-Majma (4/301), saying, "The narrators of Ahmad's chains are trustworthy, except that the route containing 'the one you most fear' was reported by Ahmad in mursal form, while Bazzar connected it with trustworthy narrators."As for the saying "there is no monasticism in Islam," I have found no basis for it. It has been reported from Yazid Faqir, from Jabir bin Abdullah, who said, the Messenger of Allah ﷺ said, "There is no divorce before marriage, no manumission for one who owns no slave, no silence from day until night as an act of worship, no fasting two days without breaking the fast between them, no suckling after weaning, no orphanhood after reaching puberty, and no monasticism among us." This report contains Saeed bin Marzuban Baqqal, who is extremely daif. Ibn Hibban transmitted it through his route in al-Majruhin (384), and Ibn Jawzi said in Ilal Mutanahiya (2/641), "This hadith is not sahih, because of Saeed bin Marzuban Baqqal, who is discarded as a narrator."As for what is reported from Abu Umama as a marfu report, "and do not be like the monasticism of the Christians," it is daif. Bayhaqi narrated it (7/78), and its chain contains Muhammad bin Thabit Basri, whom most scholars have judged daif.
