The new things that invalidate the fast (11)

The sixteenth item is: The Anal Scope:
The doctor may insert the telescope into the anus to reveal the intestine, and the same details mentioned in the stomach scope are applied here.

The seventeenth item is: anything that enters the body through the urethra, such as scope, solution, or medicine:

Do this break the fast?

Scholars have discussed this issue in the past and reached the following conclusion:

The first view is of the Hanafi, the Maliki, and the Hanbali school of Fiqh:
Dripping in the urethra does not break the fast even if it reaches the bladder.
Their evidence is: there is no outlet the inner part of the rectum and the abdomen.

The Second view is the chosen by the Shafi`i school of Fiqh that this action invalidates the fast because there is an outlet between the inner part of the rectum and the abdomen.

In modern medicine:

There is no connection between urinary tract and the digestive system: based upon this, it does not break the fast.

The eighteenth item: Blood Donation:
This is based on the issue of cupping.
The popular view is: it invalidates the fast and that is the chosen view of Ibn Taymiyah (may Allah have mercy on his soul).

The view of the majority scholars is: it does not break the fast.

The soundest and preponderant view is: it invalidates the fast.
Based on this, it is not permissible for a person to donate his blood during the fast except if there is a necessity.

The nineteenth item is: Taking a Blood Sample For Diagnosis:
This does not break the fast because it is not the same as cupping, because cupping weakens the body.

The twenty item is: Toothpaste:
It does not break the fast because it does not reach the stomach, but it is better for a person not to use it except after breaking the fast. It is enough to use the Miswak or the brush without the toothpaste. Allah knows the best.
