Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: "The daughter of the Messenger of Allah (peace and blessings be upon him) fell ill, so the Messenger of Allah (peace and blessings be upon him) said to Sayyiduna Uthman (may Allah be pleased with him): 'Stay with her, for it is necessary that either I or you remain with her, and you are more entitled to it.' So the Messenger of Allah (peace and blessings be upon him) left him behind to nurse her. Then, when Allah granted him (peace and blessings be upon him) victory, the Messenger of Allah (peace and blessings be upon him) sent him a message giving him the glad tidings that Allah had completed their number through you."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Wabarah except Mujalid, and no one narrated it from Mujalid except Ahmad bin Bashir; and Yahya al-Ju'fi is alone in narrating it."
