If we have like 50-60 Quran at out home small and big some are single Quran and some are the complete ones but only 3 or 4 of them are used for Recitation soo is it wrong to keep the other ones at home and is it better to give them in the mosque or is ok if they are just kept in the house..
Wa’alaykum as Salam wa rahmatullahi wa barakatuhu,
It is permissible to keep the extra Qurans, if you are keeping them with respect.
If it is highly unlikely that these Qurans will ever be used, it is better to donate them to a Masjid/Madrassah/Muslim school, so that when others recite from them, you will get the reward. It will be a means of Sadaqah Jaariyya for you.
