Which beneficial books do you advise us to read to our families at home?

Shaykh āliḥ Fawzān al-Fawzān:

The best thing to read to them is Riyāḍ al-āliḥīn. This book is beneficial and contains statements from the Messenger of Allah ﷺ categorised according to detailed chapters. Likewise, just as we have mentioned, read to them rulings related to prayer and ablution  so that they become aware (of these matters).
