Q: My father accompanied my grandfather, may Allah have mercy upon him, to perform Hajj in Makkah Al-Mukarramah. My father dwelt in a tent with some of his friends. Once, he went out to bring water where he found a lady's handbag. He took it and entered the tent. He found in it 500 Saudi riyals, some documents (Part No. 11; Page No. 245) and the passport of an Egyptian lady. He decided to give the bag to the neighboring Egyptian tent, but some bad friends recommended him to take the money and he did. Then, before returning to Yemen, he put the handbag in a bus of Egyptian pilgrims. This happened 20 years ago. Now my father wants to return this money but he does not know the address of the woman and he decided to give this money to a mosque to supply it with water. However, 100 Saudi riyals now equal 4200 Yemeni riyals, should my father, who is wealthy now, give this money in charity estimating its value at the time when he took it? At the time, 100 Saudi riyals equaled 130 Yemeni riyals. In addition, where should he spend that charity? Answer us, may Allah reward you with the best.
