'Abdullah bin Sahl was killed, and 'Abdullah bin Sahl was killed, and his brother 'Abdur-Rahman bin Shl, and Huwayysah, and Musayysah, his paternal cousins, came to the Messenger of Allah. 'Abdur-Rahan spoke about his brother's case, but he was the youngest of them, so the Messenger of Allah (ﷺ) said: "Let the elders speak first." So they spoke about their companions, and the Messenger of Allah (ﷺ) said: Let fifty of your swear an oath." The said: "O Messenger of Allah, it is something that we did not witness: how can we swear an oath?" He said: "Then let the Jews swear fifty oaths to their innocence."
