55. So be patient (O Muhammad صلى الله عليه وسلم). Verily, the Promise of Allâh is true, and ask forgiveness for your fault[1] and glorify the praises of your Lord in the ‘Ashî (i.e. the time period after the midnoon till sunset) and in the Ibkâr (i.e. the time period from early morning or sunrise till before midnoon) [it is said that, that means the five compulsory congregational Salât (prayers) or the ‘Asr and Fajr prayers].
