Meaning & source

Qasim was the firstborn of the Prophet ﷺ and Khadijah (RA), who died in early childhood in Makkah. From him the Prophet ﷺ took his kunya — Abu al-Qasim, father of Qasim.

In Sahih al-Bukhari the Prophet ﷺ said: name yourselves with my name, but do not take my kunya — and so the ummah carried Qasim itself instead, generation after generation.

The name inside the Prophet's ﷺ own

Qasim was the firstborn of the Prophet ﷺ and Khadijah (RA) — a son of Makkah's earliest years, born before revelation ever came, who died in early childhood. Though he lived only a short time, he occupies a special place in Islamic history, for the Prophet ﷺ became known by the honorable kunyah Abu al-Qasimfather of Qasim, because of him. Every use of the kunya remembered the child again. Grief, transformed into honor, spoken daily for decades.

Name yourselves with my name

When the Prophet ﷺ said, "name yourselves with my name, but do not take my kunya" (Bukhari 3538), the ummah listened and poured into the name Muhammad — and into Qasim itself, carried generation after generation.

The fair distributor

The name means one who divides justly. The Prophet ﷺ used that very meaning of himself: Allah is the Giver, and I am al-Qasim — the one who distributes what Allah bestows. It is a name for a rare kind of trust. The person who divides, and from whom every share comes out fair. Short in its first bearer's years. Long, very long, in honor.

What Quraysh said, and what Allah answered

Qasim was not the only son the Prophet ﷺ buried. Abdullah followed, and years later Ibrahim. Quraysh watched the graves fill and reached for the cruelest word they had: abtar — cut off, a man with no sons to carry him forward. Allah answered them in a surah of three verses, and gave the Prophet ﷺ something better than lineage: indeed, We have granted you al-Kawthar — the abundance — and then turned the insult around entirely: indeed, it is your enemy who is cut off (Surah al-Kawthar, 108:1–3). The men who mocked him are remembered now only as the ones who mocked him. The Prophet ﷺ name is said aloud, with blessings, millions of times a day.

To carry this name

To carry this name is to be a fair divider — of wealth, time, attention, and credit — and to know that a short life, honored rightly, can be remembered longer than empires.

Scholars discuss

The scholars draw out the quiet honor here: of all his ﷺ children, it was Qasim — the firstborn who died in early childhood — whose name the Prophet ﷺ carried in his own kunya for life. Every time Makkah called him Abu al-Qasim, a child who lived briefly was remembered again. The discussions around Bukhari 3538 (whether the kunya-restriction was for his ﷺ lifetime or after) are related in the fiqh literature; the name Qasim itself — the fair distributor — the ummah adopted with love, and the Prophet ﷺ used its meaning of himself: "Allah gives, and I am the distributor (qasim)."

Almost nothing of his life is preserved in hadith, and for a plain reason: he died in infancy, in Makkah, before the Prophetic mission began. Even his exact age is unknown — the historians differ, and no authentic narration settles it. What is firmly established is not biography but consequence: the kunya, repeatedly confirmed across both Sahih collections, is the strongest authenticated trace he left. Commentators also connect Surah al-Kawthar to the death of one of the Prophet's ﷺ sons, though they differ on which — Qasim, Abdullah, or Ibrahim — and this site records the connection without choosing among them.

In the hadith
