Ruqayyah (R.A.) was Rasulullah’s (Sallallahu Alaihi Wasallam) second daughter. She was married to Utba the son of Abu Lahab. Abu Lahab was the uncle of Rasulullah (Sallallahu Alaihi Wasallam) but had become his violent enemy and of Islãm and its followers.

Both father and son did not enter into Islãm and Utba repudiated Ruqayyah (R.A.) on the incitement of his father. Rasulullah (Sallallahu Alaihi Wasallam) gave Ruqayyah (R.A.) in marriage to Uthman ibn Affãn (R.A.).

When the battle of Badr took place, Ruqayyah (R.A.) was seriosly ill. Uthman (R.A.) had the desire to fight but Rasulullah (Sallallahu Alaihi Wasallam) asked him to stay at home and take care of his sick wife. He told him that he would be rewarded equal to the participants. He marked him ’Fighter of Badr’ and gave him his share in the booty.

Ruqayyah (R.A.) passed away on the day the Muslims returned victorious.
