Qasim was the eldest son of Muhammad and Khadija. After Qasim, his four sisters were born. According to early Islamic sources, Abd Allah was born before the first revelation in 610 CE, most likely between 605 and 608. He was the youngest child of Muhammad and Khadija.
Muhammad gave him the name of his father. Abd Allah died at 4 around 610 CE in Mecca, or roughly just before Muhammad's first revelation. ==Siblings==
