Sahih al-Bukhari Book 68, Hadith 42
Allah's Messenger (ﷺ) performed the Tawaf (around the Ka`ba while riding his camel, and every time he
reached the corner (of the Black Stone) he pointed at it with his hand and said, "Allahu Akbar."
(Zainab said: The Prophet (ﷺ) said, "An opening has been made in the wall of Gog and Magog like this
and this," forming the number 90 (with his thumb and index finger).
(the Maula of Munba'ith) The Prophet (ﷺ) was asked regarding the case of a lost sheep. He said, "You should take it, because it is for you, or for your brother, or for the wolf." Then he was asked about a lost camel. He got angry and his face became red and he said (to the questioner), "You have nothing to do with it; it has its feet and its water container with it; it can go on drinking water and eating trees till its owner meets it." And then the Prophet (ﷺ) was asked about a Luqata (money found by somebody). He said, "Remember and recognize its tying material and its container, and make public announcement about it for one year. If somebody comes and identifies it (then give it to him), otherwise add it to your property."
Abul Qasim (the Prophet (ﷺ) ) said, "There is an hour (or a moment) of particular significance on Friday. If it happens that a Muslim is offering a prayer and invoking Allah for some good at that very moment, Allah will grant him his request." (The sub-narrator placed the top of his finger on the palm of the other hand between the middle finger and the little one.)
