Peace be upon you. Over a year ago, I found a large black flag in my field with 'Labbayk Ya Zahra' written on it. I picked it up to keep it clean and placed it in a spot in the field. It remained there through winter and summer for that entire time. Its condition deteriorated slightly because it was already old and used, and its color faded a bit. However, due to my actions, its condition worsened slightly. Now, after some time, I heard about the flag. I asked two of my neighbors, and they said it wasn't theirs. The third neighbor, who I suspect might own it (because I once saw a black flag on his roof), said it might be his since he had a flag on his roof (I described it to him by its color and other details). I asked if I should bring it to him, and he said to keep it with me. I then asked if it belonged to his children or to him, and he said he didn't know (but he forgave me on their behalf). I told him to ask them, and if it belonged to them, it was with me. He agreed. Now, what should I do? It is still with me, but the matter has become old. How can I find a solution?
