We have to draw animals like foxes and elephants for our biology practicals but I have heard that drawing of living objects is not allowed, is that true?
Bismillah,
Asalamu Alaykom,
You will find scholars who say it is allowed to draw and paint pictures of humans and animals. Some scholars also say it is makruh so you should check the ruling of the marja you follow.
With regards to sculptures of living things, some scholars such as Sayed Sistani & Sayed Sadiq Shirazi don’t allow it on obligatory precaution.
May Allah grant you success
