Hadith 202
Jarir said that: One early morning when they were with God’s messenger some people came to him who were scantily clad, wearing striped woollen garments,* with swords over their shoulders; most, nay all of them, belonging to Mudar. God’s messenger showed signs of anger on his face because of the poverty-stricken state in which he saw them, and went in. After a little he came out and gave orders to Bilal who uttered the call to prayer and announced that the time to begin prayer had come. When the Prophet had prayed, he delivered an address in which he said, “ ‘Fear your Lord, people, who created you from one soul . . . God watches over you.’ ‘Fear God, and let a soul look to what it has sent forward for the morrow. Let a man give sadaqa from his dinars and dirhams, his clothing, his sa‘ of wheat and sa‘ of dates, even if it is only half a date.” Jarir said: One of the Ansar brought a purse which was almost too big for his hand to hold, indeed it was too big. Then people came one after the other till I saw two mounds of food and clothing, with the result that I saw the face of God’s messenger glowing as if it were golden. He then said, “If anyone establishes a good sunna in Islam he will have a reward for it and the equivalent of the rewards of those who act upon it after him, without theirs being diminished in any respect; but he who establishes a bad sunna in Islam will bear the responsibility of it and the responsibility of those who act upon it after him, without theirs being diminished in any respect.” Muslim transmitted it. *[The text has an-nimar au al-'aba, thus giving an alternative word.
