Sahih Muslim Book - 48, Hadith - 6900

حَدَّثَنِى أَبُو الطَّاهِرِ أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ أَخْبَرَنِى سُلَيْمَانُ بْنُ بِلاَلٍ عَنْ سُهَيْلِ بْنِ أَبِى صَالِحٍ عَنْ أَبِيهِ عَنْ أَبِى هُرَيْرَةَ أَنَّ النَّبِىَّ -صلى الله عليه وسلم- كَانَ إِذَا كَانَ فِى سَفَرٍ وَأَسْحَرَ يَقُولُ « سَمَّعَ سَامِعٌ بِحَمْدِ اللَّهِ وَحُسْنِ بَلاَئِهِ عَلَيْنَا رَبَّنَا صَاحِبْنَا وَأَفْضِلْ عَلَيْنَا عَائِذًا بِاللَّهِ مِنَ النَّارِ ».

It was narrated from Abu Hurairah that when the Prophet (s.a.w) was on a journey and the time just before dawn came he would say: "Samma' sami'un bi-hmdillahi wa husni bala'ihi 'alaina, rabbana sahibna wa afdil 'alaina, 'a'idhabillahi min an-nar (Let one who hears us convey our praise of Allah for His blessing upon us. Our Lord, accompany us and bestow Your Grace upon us. I seek refuge with Allah from the Fire)."
