Chapter: If a group killed or injured one man, will all have to give Diya or be punished with Al-Qisas?

A boy was assassinated. 'Umar said, "If all the people of San'a took part in the assassination I would kill them all." Al-Mughira bin Hakim said that his father said, "Four persons killed a boy, and 'Umar said (as above)." Abu Bakr, Ibn Az-Zubair, 'Ali and Suwaid bin Muqarrin gave the judgement of Al-Qisas (equality in punishment) in cases of slapping. And 'Umar carried out Al-Qisas for a strike with a stick. And 'Ali carried out Al-Qisas for three lashes with a whip. And Shuraih carried out for one last and for scratching.

We poured medicine into the mouth of Allah's Messenger (ﷺ) during his illness, and he pointed out to us intending to say, "Don't pour medicine into my mouth." We thought that his refusal was out of the aversion a patient usually has for medicine. When he improved and felt a bit better he said (to us.) "Didn't I forbid you to pour medicine into my mouth?" We said, "We thought (you did so) because of the aversion, one usually have for medicine." Allah's Messenger (ﷺ) said, "There is none of you but will be forced to drink medicine, and I will watch you, except Al-`Abbas, for he did not witness this act of yours."
