Yahya related to me from Malik from Nuaym ibn Abdullah al-Mujmir
that he heard Abu Hurayra say, "If any one of you prays and then sits
down in the spot where he has prayed, the angels ask blessings on him
saying, 'Allah, forgive him. Allah, have mercy on him.' And if he
moves from the spot where he has prayed and sits elsewhere in the
mosque waiting for the prayer, he remains in prayer until he prays."
Muwatta Malik Book 9, Hadith 62
