It is narrated from Sayyiduna Uthman bin Affan (may Allah be pleased with him) that he said: "I met the Messenger of Allah (peace and blessings be upon him) at al-Batha' (a sandy plain of Makkah), and he took my hand, and I walked along with him (peace and blessings be upon him). Meanwhile he (peace and blessings be upon him) passed by Sayyiduna Ammar and his mother Sayyidah Sumayyah (may Allah be pleased with them both) while they were being severely tortured (by the disbelievers of Makkah). So he (peace and blessings be upon him) said (consoling them and giving them glad tidings): 'Patience, O family of Yasir, for your destination is Paradise.'"
This narration is mentioned in Musnad al-Harith; its chain contains a narrator named Abd al-Aziz bin Aban, who is da'if (weak) and matruk (abandoned). However, other authentic supporting reports and narrations concerning the patience of the family of Yasir and the glad tidings of Paradise for them are found in the books of hadith and Sirah.
