People came to to the Messenger of Allah (ﷺ) and they ware dressed in woollen clothes. He (the Holy Prophet) saw their dismal state, as they were suffering from want and the rest of the hadith is the same.
Sahih Muslim Book 12, Hadith 91
← Previous Hadith When we were sitting in the company of the Messenger of Allah (ﷺ). There came people dressed in striped woollen clothes, and the rest of the hadith in the same, and there (it is also mentioned):" He observed the Zuhr prayer and then climbed up a small pulpit, praised Allah, lauded Him, and then said: Verily Allah in His Book has revealed: 'O people, fear your Lord, ' etc." (iv. 1).

Sahih Muslim Book 12, Hadith 90 Next Hadith → We were commanded to give charity (despite the fact.) that we were coolies. Abu 'Aqil donated half a sa'. And there came another man with more than this. The hypocrites said: Verily Allah does not stand in need of the charity of this, and the second one has done nothing but only made a show (of his charity). Then this verse was revealed." Those who scoff at the voluntary givers of charity among the believers as well as those who cannot find anything (to give) but with their hard labour" (ix. 80). And Bishr did not utter the word Muttawwi'in.
