It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) was on a journey and dawn began to break, he would say: 'Sami'a sami'un bi-hamdi Allahi wa ni'matihi wa husni bala'ihi 'alayna, rabbana sahibna fa-afdil 'alayna, 'a'idhan billahi min al-nar' (A listener has heard of the praise of Allah, His blessing and His excellent trial of us. Our Lord, be our Companion and bestow Your favour upon us, (I say these words) seeking refuge in Allah from the Fire). He (peace and blessings be upon him) would repeat these words three times in a raised voice. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.
