Q: The Hadith of Rasulullah Sallallahu alayhi wasallam states: "He who defends the honour of his (Muslim) brother, Allah will secure his face against the Fire on the Day of Resurrection." [Jami al-Tirmidhi]

1. I have been in situations where Muslims (especially Ulama) are defamed. This sometimes happens in face to face conversations and sometimes on social media. I feel that it is my duty to defend my Muslim brother. However, a person told me that if I do not know the background to the entire situation/incident, I should keep silent and I should not defend my Muslim brother.

I wish to ascertain whether or not I should defend my Muslim brother in such situations despite my insufficient knowledge of the entire background.

2. The person who told me this explains that if I do defend my Muslim brother in such a situation without full knowledge of the background, I am indirectly defaming and doubting the person who passed on the information. Is this the correct understanding?

Q: I am aware that generally the meat found in the restaurants of Saudi Arabia are not fit for consumption due to the method of slaughtering. Assuming that such meat is carrion, would it be permissible to eat veg food from such restaurants. E.g. buying a veg pizza from Pizza Hut. Is there any risk of contamination?

Q: I have heard that it is ok for Hanafis to masturbate if there is a serious chance of falling into sin and masturbating can help to relieve some of that sexual tension thus avoiding the sin. Is this true? If it is true, is it fine if I masturbate so that it is easier to avoid watching pornography?

Q: What is the difference between israaf and tabzeer since both translate as wasting? 

Q: I have a question regarding impurity and touch screen phones. I would like to know how invisible impurity such as urine traces or other invisible impurity may be removed from a cellphone as it cannot be washed as it would be ruined. Would wiping the dry invisible impurity with a dry cloth remove it from the smooth surface of a phone? Or how about a wet cloth that is wetted with isopropyl alcohol (as this does not harm the phone)?

Q: I am a science student and I have a bunch of math textbooks. These are strictly math textbooks as I understand. In one of the books, the author mentions solving equations in their multiple variable "incarnations". I assume the author means "form" because there is no religious meaning here as far as I can tell. In a different book, the author tells a short biography of a mathematician who was also an astrologer. The presence of such words disturbs me. I would like to know if there is something wrong with me continuing to read these textbooks and can I keep them or not. 

Q: Allah is god of everything, does it mean that Allah is god over Islam and every religion?
