وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نُعَيْمِ بْنِ عَبْدِ اللَّهِ الْمُجْمِرِ، أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ إِذَا صَلَّى أَحَدُكُمْ ثُمَّ جَلَسَ فِي مُصَلاَّهُ لَمْ تَزَلِ الْمَلاَئِكَةُ تُصَلِّي عَلَيْهِ اللَّهُمَّ اغْفِرْ لَهُ اللَّهُمَّ ارْحَمْهُ فَإِنْ قَامَ مِنْ مُصَلاَّهُ فَجَلَسَ فِي الْمَسْجِدِ يَنْتَظِرُ الصَّلاَةَ لَمْ يَزَلْ فِي صَلاَةٍ حَتَّى يُصَلِّيَ ‏.‏

Yahya related to me from Malik from Nuaym ibn Abdullah al-Mujmirthat he heard Abu Hurayra say, "If any one of you prays and then sitsdown in the spot where he has prayed, the angels ask blessings on himsaying, 'Allah, forgive him. Allah, have mercy on him.' And if hemoves from the spot where he has prayed and sits elsewhere in themosque waiting for the prayer, he remains in prayer until he prays." Translation Not Available
