Assalamualaikum,
Four or five years back my father found a mobile phone on the street and brought it home with the intention of returning it to the original owner. I was a very young at the time. I was very interested in electronics, but did not have a sound knowledge on the real world. I disassembled the phone into pieces and misplaced the sim card too. It was unable to find the real owner after that. Now, I feel really bad and want to compensate. What should I do?
