Secrecy of Private Matters (Guarding Secrets)

Abu Sa'id Al-Khudri (May Allah be pleased with him) reported:
Messenger of Allah ﷺ said, "The most evil of the people to Allah on the Day of Resurrection will be the man who consorts with his wife and then publicizes her secret."

[Muslim].

عن أبى سعيد الخدرى رضي الله عنه قال: قال رسول الله ﷺ: "إن من شر الناس عند الله منزلة يوم القيامة الرجل يفضي إلى المرأة وتفضي إليه ثم ينشر سرها" ((رواه مسلم)).

'Abdullah bin 'Umar (May Allah be pleased with them) reported:
My father 'Umar (May Allah be pleased with him) said: When (his daughter) Hafsah (May Allah be pleased with her) became a widow, I met 'Uthman bin 'Affan (May Allah be pleased with him) and offered Hafsah for marriage to him. 'Uthman said: "I shall think over the matter." I waited for a few days and then 'Uthman met me and said: "It occurred to me that I should not marry at present." Then I met Abu Bakr (May Allah be pleased with him) and said to him: "If you are willing, I shall marry my daughter Hafsah to you." Abu Bakr (May Allah be pleased with him) remained silent and did not utter any word to me in reply. I grew more angry with him than with 'Uthman. I had waited for only a few days when Messenger of Allah ﷺ asked for her hand in marriage and I married her to him. Thereafter, I met Abu Bakr (May Allah be pleased with him) who said, "Perhaps you were angry with me when you offered Hafsah to me and I said nothing in reply." I said, "Yes, that is so." He said, "Nothing stopped me to respond to your offer except that I knew that Messenger of Allah ﷺ had mentioned her and I could not disclose the secret of Messenger of Allah ﷺ. Had Messenger of Allah ﷺ left her, I would have accepted her."

[Al-Bukhari and Muslim].

وعن عبد الله بن عمر رضي الله عنهما أن عمر رضي الله عنه حين تأيمت بنته حفصة قال: لقيت عثمان بن عفان رضي الله عنه ، فعرضت عليه حفصة فقلت: إن شئت أنكحتك حفصة بنت عمر؟ قال: سأنظر في أمري. فلبثت ليالي، ثم لقيني فقال ‎: قد بدا لي أن لا أتزوج يومي هذا. فلقيت أبا بكر الصديق رضي الله عنه، فلم يرجع إلى شيئاً! فكنت عليه أوجد مني على عثمان، فلبثت ليالي، ثم خطبها النبي ﷺ، فأنكحتها إياه. فلقيني أبو بكر فقال: لعلك وجدت حين عرضت على حفصة فلم أرجع إليك شيئاً؟ فقلت: نعم. قال: فإنه لم يمنعني أن أرجع إليك فيما عرضت على إلا أني كنت علمت أن النبي ﷺ ذكرها، فلم أكن لأفشي سر رسول الله ﷺ، ولوتركها النبى ﷺ لقبلتها . ((رواه البخارى)).

'Aishah (May Allah be pleased with her) reported:
On one occasion all the wives of the Prophet ﷺ were with him when his daughter, Fatimah (May Allah be pleased with her) who walked after the style of his father, came there. He ﷺ welcomed her saying, "Welcome, O my daughter", and made her sit on his right side, or on his left side and then whispered something to her at which she wept bitterly. When he perceived her grief, he talked secretly to her again and she smiled (with happiness). I said to her: "Messenger of Allah (ﷺ chose you from amongst all his wives to speak secretly to you and yet you cried." When he left, I asked her, "What did Messenger of Allah ﷺ say to you?" She said, "I will not divulge the secret of Messenger of Allah ﷺ." When Messenger of Allah ﷺ passed away, I said to her: "I adjure you by the right I have in respect of you to tell me what Messenger of Allah ﷺ had told you." She said: "Now (when Messenger of Allah ﷺ has died), I will tell you. When he whispered to me the first time, he told me, 'Jibril (Gabriel) used to listen to my recitation of the Qur'an and then recite it back to me once or twice a year, and this time he has done it twice; and so I perceive that my death is approaching. Then be mindful of your duty to Allah and be patient and steadfast, for I shall be an excellent predecessor for you.' On this I wept as you saw. When he perceived my distress he talked to me secretly the second time and said, 'O Fatimah, are you not pleased that you will be the chief among the believing women or of this Ummah?' This made me smile as you saw."

[Al-Bukhari and Muslim].

وعن عائشة رضي الله عنها قالت: كن أزواج النبى ﷺ عنده، فأقبلت فاطمة رضي الله عنها تمشى، ما تخطئ من مشية رسول الله ﷺ شيئاً، فلما رآها رحب بها وقال: “مرحباً بابنتى” ثم أجلسها عن يمينه أو عن شماله، ثم سارها فبكت بكاء شديداً، فلما رأى جزعها سارها الثانية فضحكت، فقلت لها: خصك رسول الله ﷺ من بين نسائه بالسرار، ثم أنت تبكين ! فلما قام رسول الله ﷺ سألتها: ما قال لك رسول الله ﷺ ؟ قالت: ما كنت لأفشي على رسول الله ﷺ سره. فلما توفي رسول الله ﷺ قلت: عزمت عليك بما لي عليك من الحق، لما حدثتني ما قال لك رسول الله ﷺ؟ فقالت: أما الآن فنعم، أما حين سارني في المرة الأولى فأخبرني “أن جبريل كان يعارضه القرآن في كل سنة مرة أو مرتين، وأنه عارضه الآن مرتين، وإني لا أرى الأجل إلا قد اقترب، فاتقى الله واصبرى، فغنه نعم السلف أنا لك” فبكيت بكائى الذى رأيت. فلما رأى جزعى سارنى الثانية، فقال: "يا فاطمة أما ترضين أن تكونى سيدة نساء المؤمنين، أو سيدة نساء هذه الأمة” فضحكت ضحكى الذى رأيت". ((متفق عليه)) ((وهذا لفظ مسلم)).
