Ka‘b b. ‘Ujra said that the Prophet came to the mosque of the B. ‘Abd al-Ashhal and prayed the sunset prayer in it. When the people finished their prayer he saw them performing tasbih after it and said, “This is the prayer to be observed at home.”* * This refers to supererogatory prayers. Tasbih is the utterance of 'Glory be to God!’ Abu Dawud transmitted it. In the version by Tirmidhi and Nasa’i it says that the people got up and offered supererogatory prayers, whereupon the Prophet said, “Observe this prayer at home.”
Reported by Abu Dawud (No. 1300). Cited in Mishkat al-Masabih (No. 1182).
"Do not turn your houses like graves, and do not take my grave a place for celebration, and invoke (Allah's) blessings upon me, for your invoking of Allah's blessings upon me will reach me wherever you may be."
