Assalamu Alaykum Wa Rahmatullahi Wa Barakatuh
I would like to begin by mentioning that Islam always encourages its followers to follow good habits and to maintain them and not fall out of them. A part of this is what many scholars mention in their books of Fiqh about making up acts of worship that have been missed. This is not only for compulsory acts of worship, like the five daily prayers and fasting of Ramadan, but also for many non-compulsory Sunnah/Mustahab acts of worship, like the daily Adhkar in the morning and evening, as long as it is your habit to do it on time. There is, however, no sin on the person if they are missed.
For example, if you have been doing morning thikr for more than three days consecutively, then you woke up late one day and the time of Fajr has finished (i.e. the sun has risen) before you could read the morning thikr, you should make it up even after the original time of it has ended.
Another example is the sunnah prayers before and after the five prayers, which are known as ‘rawatib’. If they are a habit, they should be made up for, if missed.
Also, the ghusul (baths) that are Sunnah, such as ghusul of Eid and Jummah – according to the majority of scholars – should be made up for, if missed.
Imam Abu Bakr Shataa says in his book ‘Laanat at-Talibin’:
يسن قضاء غسل الجمعة – كسائر الأغسال المسنونة
In English, “It is Sunnah to make up the ghusul of Jummah as well as the other non-compulsory ghusuls”.
And Allah knows best.
