Narrated to me ʿAmr ibn Sawwād al-ʿĀmirī: ʿAbd Allāh ibn Wahb informed us: ʿAmr ibn al-Ḥārith informed us, from Bukayr ibn al-Ashajj, from Yazīd, the freed slave of Salamah ibn al-Akwaʿ, from Salamah ibn al-Akwaʿ — may God be pleased with him — that he said: "We were during Ramaḍān in the time of the Messenger of God, peace and blessings be upon him — whoever wished fasted, and whoever wished broke the fast and ransomed [it] by feeding a poor person, until this verse was revealed: 'So whoever among you witnesses the month, let him fast it.'"
