Abd Allah ibn Uthman (Arabic: عبد الله ابن عثمان, romanized: ʿAbd Allāh ibn ʿUthmān‎; c. 620 – November 625), was the son of the third caliph Uthman (r. 644–656) and Ruqayya bint Muhammad.

[1] Born in Abyssinia, Abd Allah was the first grandson of the Islamic prophet Muhammad.

[8] Mus'ab al-Zubayri narrated that when Uthman migrated to Abyssinia, he was accompanied by his wife Ruqayya bint Muhammad.

She died later in the month, on the day when Zayd ibn Haritha returned to Medina with news of their victory at the Battle of Badr.

Abd Allah died after a rooster bit his eye in November 625 (Jumada al-Thani 4 AH) at the age of five.
