Hazrat Hakeemul Ummat Mawlana Ashraf Ali Thanawi ra said;

“Routine daily ma’moolat (wird), though it may be nawafil (extra/noncompulsory worship) should not be skipped at all, as much as possible.

If they can not be executed at their scheduled time, they must be done later.

Harms of skipping them all together is evident from this saying:

من لا ورد لہ لا وارد لہ

(That is, an individual without a wird is at loss and does not recieve Divinely guiding thoughts.)
