It is narrated from Sayyiduna Amr bin Harith (may Allah be pleased with him) that he heard the Messenger of Allah (peace and blessings be upon him) reciting «‏‏‏‏﴿إِذَا الشَّمْسُ كُوِّرَتْ﴾» ‏‏‏‏ in the Fajr prayer. When he (peace and blessings be upon him) reached this verse «﴿وَاللَّيْلِ إِذَا عَسْعَسَ﴾» , I began to wonder in my heart what is the meaning of «﴿وَاللَّيْلِ إِذَا عَسْعَسَ﴾» (when the night declines).
