Desirability of offering Nawfil (Voluntary or Optional) Prayers at Home

Ibn 'Umar (May Allah be pleased with them) reported:
The Prophet ﷺ said, "Observe part of the [Nawafil (voluntary)] Salat (prayers) in your homes. Do not turn your homes into graves."

[Al-Bukhari and Muslim].

وعن ابن عمر رضي الله عنهما عن النبي ﷺ قال: اجلعوا من صلاتكم في بيوتكم، ولا تتخذوها قبورًا". ((متفق عليه)).

Jabir (May Allah be pleased with him)reported:
The Messenger of Allah ﷺ said, "When you have finished your (Fard) Salat (prayer) in the mosque, you should observe some of your (Sunnah and Nawafil) Salat at home; Allah will bless your homes because of your Salat (in your homes)."

[Muslim].

وعن جابر رضي الله عنه قال: قال رسول الله ﷺ : "إذا قضى أحدكم صلاته في مسجده، فليجعل لبيته نصيبًا من صلاته، فإن الله جاعل في بيته صلاته خيرًا". ((رواه مسلم)).

'Umar bin 'Ata reported that Nafi' bin Jubair sent him to Sa'ib bin Ukht Namir to ask him about something that Mu'awiyah had seen him doing in Salat (prayer). He said:
"Yes, I performed the Friday prayer along with him in the enclosure (Maqsurah), and when the Imam concluded the Salat with Taslim, I stood up in my place and performed the Sunnah prayer. When Mu'awiyah went home, he sent for me (and when I came) he said: "Never do again what you have done. When you have observed the Friday prayer, you must not start another Sunnah prayer till you have spoken to some one or have shifted your place; because the Messenger of Allah ﷺ ordered us not to follow up the congregational Salat with any other Salat until we have talked (to some one) or moved from the place."

[Muslim].

وعن عمر بن عطاء أن نافع بن جبير أرسله إلى السائب ابن أخت نمر يسأله عن شيء رآه منه معاوية في الصلاة فقال: نعم صليت معه الجمعة في المقصورة، فلما سلم الإمام، قمت في مقامي، فصليت فلما دخل أرسل إلي فقال: لا تعد لما فعلت: إذا صليت الجمعة فلا تصلها بصلاة حتى تتكلم أو تخرج، فإن رسول الله ﷺ أمرنا بذلك أن لا نوصل صلاة بصلاة حتى نتكلم أو نخرج. ((رواه مسلم)).
