Narrated Abu Mas`ud Al-Ansari: Once a man said to Allah's Apostle "O Allah's Apostle! I may not attend the (compulsory congregational) prayer because so and so (the Imam) prolongs the prayer when he leads us for it. The narrator added: "I never saw the Prophet more furious in giving advice than he was on that day. The Prophet said, "O people! Some of you make others dislike good deeds (the prayers). So whoever leads the people in prayer should shorten it because among them there are the sick the weak and the needy (having some jobs to do).

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."

Narrated Abu Musa: The Prophet was asked about things which he did not like, but when the questioners insisted, the Prophet got angry. He then said to the people, "Ask me anything you like." A man asked, "Who is my father?" The Prophet replied, "Your father is Hudhafa." Then another man got up and said, "Who is my father, O Allah's Apostle ?" He replied, "Your father is Salim, Maula (the freed slave) of Shaiba." So when `Umar saw that (the anger) on the face of the Prophet he said, "O Allah's Apostle! We repent to Allah (Our offending you).
