Respect women’s rights in Islam , be just towards widows in society , show compassion towards those who have lost their spouses etc..

This hadith discusses the rights of a pregnant widow to remarry after her husband's death. It is narrated by Yahya from Malik from Abdu Rabbih ibn Said ibn Qays that Abu Salama Ibn Abd ar-Rahman said that Abdullah Ibn Abbas and Abu Hurayra were asked when a pregnant woman whose husband had died could remarry. Ibn Abbas said that she should wait until two periods have passed before she can remarry while Abu Hurayra said that she can marry as soon as she gives birth. Umm Salama was then consulted on this matter and she told them about Subaya al-Aslamiya who gave birth half a month after her husband's death and two men asked to marry her; one young man and one old man. She chose the young man but the old man argued that she was not free to marry yet since her family was away at the time. Subaya then went to Prophet Muhammad who declared that she was free to marry whomever she wished. This hadith teaches us about the rights of widows in Islam; they are allowed to remarry once they have given birth or waited for two periods if they are still pregnant at their husbands' deaths.
