Can I lie to protect good deeds? Like if i pray tahajuud while my wife is asleep and she when she wakes up for fajr she asks me did you pray tahajjuud i can say no ive just woken up for fajr too?

Ustadh AbdulAziz al-Haqqan

If she asks say yes I did why lie? And tell her I prefer that you don't ask as I want it to be between me and my Creator.
