Folding one's hands in the last rakaat of the sunnats of fajr while sitting and performing salaah

Q: If sitting down and performing sunnat of Fajr, after the last sajdah of the salah, one puts their hands up again for Surah Fatiha, but remembers before reciting anything, and then goes to continue tashahudd, should a qadha be recited for this salah? And should one have made sajdah sahw in such a case .

Can the Imaam al-Muslimeen compel someone to discharge his zakaat

Q: I would like to inquire: if an individual deliberately refuses to pay Zakaat, does the Imaam al-Muslimeen have the authority to compel him to discharge this obligatory duty? 

I have read that the Fuqaha make a distinction between amwaal-e-zahirah and amwaal-e-batinah. Could you kindly explain this further and provide references from the books of Fiqh?

Carmine

Q: I’d like to enquire about the permissibility of the consumption of carmine. I have tried to research this matter on the muftionline site but mainly see the answer to avoid it. I’d like clarification on it being a halaal/haraam item thus its permissibility. 

I personally don’t consume it, yet a lot of products contain carmine & sometimes those from Arab countries that bear halaal logos, not finding a direct answer about its permissibility makes it a bit more difficult to warn family members from it’s consumption.

Moving into a house with some stuff of the old owner

Q: I have moved into a new home. The previous owner was not Muslim. He had left some baking trays that fit into the oven that he left here which I presume he was not using. I am not sure if he would have cooked any haraam food with the trays. I wanted to throw his trays away but now some of my baking trays were placed in the same draw and they got mixed up so I don't know which are mine and which are his. Is it fine if I end up using the dishes that he used to cook with as long as its washed with sunlight and water?
