Many scholars are asked about whether using injection during fasting in Ramadan breaks the fast (roza) or is it allowed to use it?
Scholars have difference of opinion on this matter and they give different opinion about this problem. When Dr. Zakir Naik was asked about injection he said that if any sort of nourishment is provided through these injection or drip then this will break the fast otherwise it’s permissible.
When Mufti Tariq Masood was asked the same question he said its permitted to use injection and drip as it will not affect the fasting even if its glucose or nourishment.
Mufti Muhammad Akmal Madani discussed the difference of opinion among scholars on this issue and said that I prefer the view that injections should be avoided until or unless they are necessary.
He further said that if not using injection will cause health problems then you should use it during fasting otherwise it should be delayed until sunset.
