It really depends on the route you take. If you fly to KL with Iran air and then take a flight to Singapore, It would be around 9-10 hours total but flying to one of the Arab countries from tehran and then going to Singapore might take longer. However it all depends on the weather conditions etc. I have travelled the route quiet a few times never got there in less than 8:40 and the longest took me about 11 coming from s'pore to tehran.
