Aisha (may Allah be pleased with her) narrated: I said to the Prophet (peace and blessings be upon him): "It is enough for you regarding Safiyyah (peace and blessings be upon her) that she is such and such," meaning that she is short in stature. The Prophet (peace and blessings be upon him) said: "You have uttered a word which, if mixed with the sea, would overwhelm it (i.e., it would change its nature)." Its chain is authentic. Narrated by Ahmad, al-Tirmidhi, and Abu Dawood.
