Mu'jam Kabir Tabarani 277 — from his father, Sayyiduna Abd al-Rahman

Abu Salamah bin Abd al-Rahman bin Awf narrates from his father, Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him), who said: The Messenger of Allah (peace and blessings be upon him) was asked: Which part of the night is most listened to (for supplication)? He (peace and blessings be upon him) said: "The middle of the last part of the night. Then prayer is accepted until the Fajr prayer is performed; then there is no prayer for a while until the sun has risen the measure of one or two spears; then prayer is accepted until the shadow stands upright like a spear; then there is no prayer until the sun passes the meridian; then prayer is accepted until the sun is at the measure of one or two spears (above the horizon); then there is no prayer until the sun sets." The narrator said: Then he (peace and blessings be upon him) said: "Any Muslim man who frees a Muslim man, that is his release from Hell: for every bone of the one freed, a bone of the one who frees will be saved (from Hell). And any Muslim woman who frees a Muslim woman, that is her release from Hell: for every bone of the one freed, a bone of the one who frees will be saved (from Hell). And any Muslim man who frees two Muslim women, the two of them are his release from Hell: for two bones of theirs, one bone of his will be saved."
