It is reported in Tabrani that if for some reason a person misses his normal recitation of the day, or misses some particular forms of dhikr that are part of his daily routine, he will still be rewarded for it if he recites the following three verses of Surah Room:
30:17 So glorify Allah, when you enter the evening, and when you enter the morning.
30:18 And His is all the praise in the heavens and the earth; and when the day begins to decline and at noon.
30:19 He brings out the living from the dead, and brings out the dead from the living. And He revives the earth after its death. And thus shall you be brought out.
