Abu al-Ala (may Allah have mercy on him) relates: "We were in al-Mirbad when a Bedouin came to us with a piece of leather and said: 'Look at what is written on it.' It was a letter from the Messenger of Allah (peace and blessings be upon him) to Banu Zuhayr bin Uqaysh (a branch of the tribe of Ukl): 'If you establish the prayer, pay the zakah, and give a fifth of whatever spoils of war you gain, as well as the share of the Prophet (peace and blessings be upon him) and the safi (the selected portion), then you are safe under the protection of Allah.' I said: 'Did you yourself hear this from the Messenger of Allah (peace and blessings be upon him)?' He said: 'I heard him (peace and blessings be upon him) say: Fasting the month of patience (Ramadan) and three days of every month removes the rancour and impurity of the chest.'
We said: 'Did you yourself hear this from the Messenger of Allah (peace and blessings be upon him)?' He said: 'I see that you suspect me.' Then he took the sheet and went off quickly. We asked about him and were told: 'This is al-Namir bin Tawlab al-Ukli.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Khallad bin Qurrah except Muhammad bin Sallam."
