Sahih Muslim Book - 5, Hadith - 1510

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِى الزِّنَادِ عَنِ الأَعْرَجِ عَنْ أَبِى هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- قَالَ « لاَ يَزَالُ أَحَدُكُمْ فِى صَلاَةٍ مَا دَامَتِ الصَّلاَةُ تَحْبِسُهُ لاَ يَمْنَعُهُ أَنْ يَنْقَلِبَ إِلَى أَهْلِهِ إِلاَّ الصَّلاَةُ ».

It was narrated from Abu Hurairah that the Messenger of Allah (s.a.w) said: "One of you is still in a state of prayer so long as the prayer is keeping him there, and nothing is keeping him from going back to his family except the prayer."
