حَدَّثَنَا يَعْقُوبُ بْنُ حُمَيْدِ بْنِ كَاسِبٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي حَازِمٍ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ إِذَا أَصْبَحْتُمْ فَقُولُوا اللَّهُمَّ بِكَ أَصْبَحْنَا وَبِكَ أَمْسَيْنَا وَبِكَ نَحْيَى وَبِكَ نَمُوتُ وَإِذَا أَمْسَيْتُمْ فَقُولُوا اللَّهُمَّ بِكَ أَمْسَيْنَا وَبِكَ أَصْبَحْنَا وَبِكَ نَحْيَى وَبِكَ نَمُوتُ وَإِلَيْكَ الْمَصِيرُ ‏"‏ ‏.‏

It was narrated from Abu Hurairah that : the Messenger of Allah (saas) said: "In the morning say: 'Allahumma bika asbahna, wa bika amsayna, wa bika nahya, wa bika namut (O Allah, by Your leave we have reached the morning and by Your leave we reach the evening, and by Your leave we live and by Your leave we die). And when evening comes, say: Allahumma bika amsayna, wa bika asbahna, wa bika nahya, wa bika namut, wa ilaykal-masir (O Allah, by Your leave we have reached the evening and by Your leave we reach the morning, and by Your leave we live and by Your leave we die, and unto You is our return)."
