1) Surah At Taubah verse 36, regarding the 4 sacred month and dont be unjust to ourselves during that month.
If let say we doing something unjust to ourselves and realized about this how to repent? Any extra thing we need to perform instead solat and dua?
2) Surah At Taubah verse 34-35, about gold. As I have heard before, some say we can save gold and some say cannot for safety measure. We should do saving something can be use by others example land, house etc. My question is if let say I plan to buy house later, instead of saving money in bank I deposit money in bank as a price of gold. Later if i want we can withdraw the deposit base on price of gold. Is it permitted?
