'Aishah (May Allah be pleased with her) reported: If the Messenger of Allah ﷺ missed his night (Tahajjud) Salat because of indisposition or the like, he would perform twelve Rak'ah during the day. Muslim.
The Prophet ﷺ was an example for all of us in how he conducted himself in his daily life and this hadith serves as a reminder for us to follow in his footsteps when it comes to fulfilling our religious duties. We should strive to pray regularly and not let anything get in the way of doing so. If something does come up that prevents us from praying at its designated time then we should try our best to make it up later on so that we can still fulfill our obligations towards Allah SWT.
