The story of a bird that complained to the Prophet (peace and blessings be upon him) about losing its chicks

Abd al-Rahman bin Abdullah bin Mas'ud narrates from his father, Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him), who said: We were with the Messenger of Allah (peace and blessings be upon him) on a journey, and we passed by a tree in which there were two chicks of a small bird (a hummarah), and we took them. The bird came to the Messenger of Allah (peace and blessings be upon him) and began crying out, so the Prophet (peace and blessings be upon him) said: "Who has distressed this (bird) over its chicks?" We said: "We did." He (peace and blessings be upon him) said: "Put them (the chicks) back."
This hadith has a sahih (authentic) chain, and they (the two Shaykhs) did not record it.

It is narrated from Sayyiduna Adi bin Hatim (may Allah be pleased with him) that he said: I said: "O Messenger of Allah (peace and blessings be upon him), we hunt game and we find no knife except a sharp-edged stone or a split piece of stick." He (peace and blessings be upon him) said: "Make the blood flow (that is, slaughter it) with whatever you wish, and mention the name of Allah, the Mighty and Majestic."
This hadith is sahih (authentic) on the condition of Imam Muslim, and the two Shaykhs (Bukhari and Muslim) did not record it. The Book of Slaughtering (Kitab al-Dhaba'ih) is completed here, and now the Book of Repentance and Turning to Allah (Kitab al-Tawbah wa al-Inabah) begins.
