It is narrated from Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) that a Bedouin came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! Teach me a deed that will admit me into Paradise. He (peace and blessings be upon him) said: "Although you have made your words brief, you have asked about something very great: free a soul and release a neck." He said: Are these two not one and the same thing? He (peace and blessings be upon him) said: "No! Freeing a soul means that you alone take on the responsibility of freeing it, while releasing a neck means that you assist in paying its price. Also included in this are lending a milch animal for its benefit, and doing kindness to an oppressive close relative (who does not keep ties of kinship). Then if you are not able to do that, feed the hungry, give water to the thirsty, enjoin good and forbid evil; and if you are not able to do even that, then restrain your tongue from everything except good." This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs (Bukhari and Muslim) did not record it.
