Abul Huwairith said that God’s Messenger wrote to ‘Amr b. Hazm when he was in Najran telling him to observe the prayer early on the day of sacrifice and late on the day of the breaking of the fast, and to admonish the people.
On a festival day when I was present at the prayer along with the Prophet he first observed the prayer without adhan or iqama before the sermon. Then when he finished the prayer he stood up leaning on Bilal, praised and extolled God, gave the people an exhortation and an admonition and urged them to obey Him. He then went to the women, taking Bilal with him, commanded them to fear God and gave them an exhortation and an admonition.
