Abdullah ibn Abi Bakr

Eldest son of Abū Bakr al-Ṣiddīq, older than ʿĀʾishah but younger than Asmāʾ. ʿĀʾishah described him as: "a young, strong man, very intelligent and quick to understand" (ghulāmun shābbun thaqifun laqin). He played a critical intelligence role during the three days the Prophet ﷺ and Abū Bakr were hidden in the Cave of Thawr.

His assignment: each morning he would walk through Makkah as if going about his normal daily chores, visiting the market, tending to goats, while listening closely to whatever people were discussing. Where were the Quraysh sending search parties? Which direction were they heading? What were the latest rumors? He would then go to the cave at night with food and supplies and brief the Prophet ﷺ and Abū Bakr on everything he had heard, so they could adapt their plan if needed. Because he was young, no one paid him special attention.

He accepted Islam formally and later emigrated to Madinah himself.
