ʿAbd-Allāh ibn Jaḥsh (Arabic: عَبْد ٱلله ابْن جَحْش) (c. 586 – 625[1]), was the brother-in-law and companion of the Islamic prophet, Muhammad.
[3]: 33 The family had formed an alliance with Harb ibn Umayyah and his son Abu Sufyan.
[1]: 66 He married Fatima bint Abi Hubaysh,[3]: 173 who was a cousin of Khadijah from the Asadi clan of the Quraysh,[2]: 82, 339 and they had one son, Muhammad.
[2]: 215 Muhammad dispatched ibn Jahsh on the Nakhla Raid in Rajab A.H. 2 (October 623), together with seven other Emigrants and six camels.
When the Quraysh caravan passed through Nakhlah, Abd-Allah urged his companions to attack the merchants despite the fact that it was still the sacred month of Rajab, when fighting was forbidden.
