As salam aleykom wa rahmatullah wa barakatuh, Ustadh In a household where both my husband and I can read Arabic but slowly, is it better for us to aim to complete the Qur’an over and over or to try and read al-Baqarah over and over together in the house even if we can’t finish it every 3 days ?

Ustadh AbdulAziz al-Haqqan
There is no authentic hadith tying al-Baqarah to every three days. It is up to you, because if you want to memorize the baqarah this is a very effective strategy.
