It is haraam, as an obligatory precaution, to touch the Name of Allah, without Wudhu, in whichever language it may have been written. And it is also haraam to touch, without Wudhu, the blessed names of the Holy Prophet of Islam, the holy Imams and Hazrat Fatima Zahra (peace be upon them). [1]   As for names which contain the name "Allah" (either as a prefix or as a suffix) like "Habibullah", there is problem (Ishkaal) in touching "Allah" without Wudhu? [2]

However, the word "Israel' in Hebrew means someone who under God's control, contrivance and servitude. Thus, it gives a meaning close to "Abdullah" in Arabic. [3] In any case, the word "Israel" [4] is the title of Ya'qub son of Isaac son of Ibrahim. It is necessary to respect this word in ordinary situations and when the word is considered all by itself. However, since this name is the standard for combat against Islam and it is a sign of animosity with Muslims, therefore, there is no objection in touching it and stepping on it deliberately to condemn and protest the enemies of Islam. [5]

In regards to the foregoing questions, Ayatollah Mahdi Hadavi Tehrani's view is as under:

Answer 1: It is haraam to disrespect God. Therefore, if a person does an action which is considered to be disrespectful and an insult to God, it is haraam.  But if an action does not have such an implication and the person doing it does not have such an intention, it is permissible. Therefore, if a person touches God's name without intending any insult and it is not considered as an insult by people either, it is permissible, thought it is makrooh and the precaution is to avoid doing such an act. The position is the same with names of prophets, the Imams and Fatima Zahra (peace be upon them).

Answer 2, 3, 4: The answer to these questions can be obtained from the answer to the first question. Of course, in regards to the third question, it should be noted that the criterion is the Urf (custom) of the wise or the custom of the same society in which this action takes place.
