"Indeed there has been an excellent example for you in Ibraaheem (Abraham) and those with him, when they said to their people: "Verily, we are free from you and whatever you worship besides Allaah, we have rejected you, and there has started between us and you, hostility and hatred for ever, until you believe in Allaah Alone," except the saying of Ibraaheem (Abraham) to his father: "Verily, I will ask for forgiveness (from Allaah) for you, but I have no power to do anything for you before Allaah, "Our Lord! In You (Alone) we put our trust, and to You (Alone) we turn in repentance, and to You (Alone) is (our) final Return," [Al-Mumtahanah (60):4]

Narrated Zaid bin Khalid Al-Juhani:

A man asked the Prophet about the picking up of a "Luqata" (fallen lost thing). The Prophet replied, "Recognize and remember its tying material and its container, and make public announcement (about it) for one year, then utilize it but give it to its owner if he comes." Then the person asked about the lost camel. On that, the Prophet got angry and his cheeks or his Face became red and he said, "You have no concern with it as it has its water container, and its feet and it will reach water, and eat (the leaves) of trees till its owner finds it." The man then asked about the lost sheep. The Prophet replied, "It is either for you, for your brother (another person) or for the wolf." [The Book of Knowledge Volume 1, Book 3, Hadeeth 91]
