Salam Alaikum
Its Jawairiya RA or Juwairiyah RA
She was the daughter of Harith and was a widow. She was a captive of war and set free by Sayyiduna Rasulullah (sallal laahu alaihi wasallam) who married her in 5 A.H. As a result of her marriage, the prisoners which belonged to her tribe were set free. This made many accept Islam.
Sayyadah Juwairiyah (radi Allahu anha) was a highly self-respecting person. She was very religious-minded and spent most of her time in Salaah. She was also very learned. She passed away at the age of 65 years in 56 A.H. and lies buried in Jannatul Baqi.
