When the Messenger of Allah ﷺ finished the battle of Badr, he sent two bearers of good news to the people of Madinah. He sent Zayd bin Haritha to the people of the lower district, and he sent Abdullah bin Rawaha to the people of the upper district, to give them the glad tidings of Allah's victory granted to His Prophet ﷺ. Zayd bin Haritha arrived just as his son Usama had finished leveling the earth over the grave of Ruqayyah, daughter of the Messenger of Allah ﷺ.
لما فرغ رسول الله ﷺ من بدر بعث بشيرين إلى أهل المدينة، بعث زيد بن حارثة إلى أهل السافلة، وبعث عبد الله بن رواحة إلى أهل العالية يبشرونهم بفتح الله على نبيه ﷺ، فوافق زيد بن حارثة ابنه أسامة حين سوى التراب على رقية بنت رسول الله ﷺ.
