a man entered the Msjid on a Friday when the Messenger of Allah was delivering the Khutbah, and he said: "Pray two Rak'ahs." Then he came on the following Friday, when the Prophet was delivering the Khutbah and he said: "Pray two Rak'ahs." Then he came on the third Friday, when the Prophet was delivering Khutbah and he said: "Pray two Rak'ahs." Then he said: "Give in charity." So they gave in charity, and he gave him (that man) two garments. Then he said: "Give in charity" and (that man) threw one of his two garments. The Messenger of Allah said: "Have you not seen this man? He entered the Masjid in scruffy clothes and I hoped that you would notice him, and give charity to him, but you did not do that, So I said, 'Give in charity.' You gave in charity, and I gave him two garments, then I said; 'Give in charity' and he threw one of his two garments. Take your garment." And he rebuked him.
Sunan an-Nasa'i Book 23, Hadith 102
Once the Prophet (ﷺ) was riding his camel and a man was holding its rein. The Prophet (ﷺ) asked, "What is
the day today?" We kept quiet, thinking that he might give that day another name. He said, "Isn't it the
day of Nahr (slaughtering of the animals of sacrifice)" We replied, "Yes." He further asked, "Which
month is this?" We again kept quiet, thinking that he might give it another name. Then he said, "Isn't it
the month of Dhul-Hijja?" We replied, "Yes." He said, "Verily! Your blood, property and honor are
sacred to one another (i.e. Muslims) like the sanctity of this day of yours, in this month of yours and in
this city of yours. It is incumbent upon those who are present to inform those who are absent because
those who are absent might comprehend (what I have said) better than the present audience."
Sahih al-Bukhari Book 3, Hadith 9
Malik related to me that Safwan ibn Sulaym said, "The Messenger
of Allah, may Allah bless him and grant him peace, was asked, 'Can the
mumin be a coward?' He said, 'Yes.' He was asked, 'Can the mumin be a
miser?' He said, 'Yes.' He was asked, 'Can the mumin be a liar?' He
said, 'No.' "
