Be mindful of your actions during both day time & night time; Strive to do good deeds during both times; Reap rewards from Allah in this life & hereafter.

This hadith is about distinguishing between day and night. It was narrated by Adiyy bin Hatim who asked the Prophet Muhammad about a verse in the Quran which states that day and night are distinguished by a white thread and a black thread. The Prophet Muhammad explained that this refers to the whiteness of day time and the darkness of night time. This hadith teaches us to be mindful of our actions during both day time as well as night time since they are both distinct from each other. We should strive to do good deeds during both times so we can reap rewards from Allah in this life as well as in the hereafter.
