Qutayla ukht al-Nadr

Qutayla ukht al-Nadr (Arabic: قُتيلة أخت النضر, or Qutayla bint al-Nadr) was a seventh-century CE Arab woman of the Quraysh tribe, noted as one of the earliest attested Arabic-language poets on account of her famous elegy for Nadr ibn al-Harith.

[1][2] After the battle of Badr in 624 CE, al-Harith was captured and, in retaliation, Muhammad ordered his execution in hands of Ali.

[7] There was also a tradition, attested in one medieval source, al-Jāḥiẓ in his Kitāb al-Bayān wa ’l-tabyīn, that she was actually called Laylā.

[10] 'Although doubt has been expressed regarding their authenticity ... these verses, frequently cited and highly appreciated, have perpetuated alNadr's memory'.

She does not call for vengeance but for a modification of behavior, a kind retroactive display of restraint and forbearance'.
