I am diabetic. Is it permissible to get an Insulin injection during fasting if it is absolutely necessary, Thank you.

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.

Being injected with a nutritious product (food or drink) invalidates Fasting. If the injection is for treatment, it is more likely that it does not nullify fasting as it does not go against the wisdom behind fasting and the characteristics of things that annul fasting do not apply to it.

So, insulin injection does not nullify fasting even if injected without any apparent necessity.

Allaah knows best.
