It is narrated from Sayyidah al-Sawda' (may Allah be pleased with her) that she said: "I came to the Messenger of Allah (peace and blessings be upon him) to give him the pledge of allegiance, and he (peace and blessings be upon him) said: 'Go and apply dye (henna to your hands), then come to me so that I may take your pledge.'"
This hadith is not narrated from Sayyidah al-Sawda' (may Allah be pleased with her) except with this chain, and Na'ilah is alone in narrating it.
