Al-Zubayr bin Bakkar states: Sayyiduna al-Qasim (may Allah be pleased with him) was born to the Prophet (peace and blessings be upon him), and he was the eldest of his children; then Sayyidah Zaynab (may Allah be pleased with her) was born; then Sayyiduna Abdullah (may Allah be pleased with him), who was also called al-Tayyib and also called al-Tahir; he was born after the proclamation of prophethood and passed away in infancy. Then Sayyidah Umm Kulthum (may Allah be pleased with her), then Sayyidah Fatimah (may Allah be pleased with her), and then Sayyidah Ruqayyah (may Allah be pleased with her) were born. This is the order of the children. Sayyiduna al-Qasim (may Allah be pleased with him) passed away in Makkah, then Sayyiduna Abdullah (may Allah be pleased with him) passed away.
Al-Tabarani recorded it, and its narrators are thiqat (trustworthy).
