Sayyidah Aishah (may Allah be pleased with her) said that when Zayd bin Harithah (may Allah be pleased with him), Ja'far (may Allah be pleased with him) and Abdullah bin Rawahah (may Allah be pleased with him) were martyred, the Messenger of Allah (peace and blessings be upon him) sat in the mosque and grief was evident on his (peace and blessings be upon him) face, and she mentioned the incident.
