It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) had al-Ajlani and his wife undergo li'an (mutual imprecation), and the woman was pregnant. The woman's husband said: By Allah, I have not gone near her since we did the 'afr of the palm trees ('afr means watering the palm trees once after they have been left unwatered from the wells for two months). So the Messenger of Allah (peace and blessings be upon him) said: "O Allah, make the truth clear." And it is said that the woman's husband had thin shins and forearms and reddish hair, while the man to whom she was attributed was Ibn al-Sahma'. (The narrator) said: Then the woman gave birth to a boy who was black, broad-foreheaded, with curly hair, thick forearms and stout shins.
