Answered by Shaykh Faraz Rabbani
Can I delay praying my post-fard sunna prayers, if I do end up praying them within the time?
Walaikum assalam,
It is valid to delay praying the sunnas (but performing them within the time. However, this diminishes the reward. It is optimal to pray the post-fard sunnas without any worldly activity taking place between the fard prayer and the sunnas that follow it.
Walaikum assalam,
