Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) said: "There are two characteristics that cannot be found together in a believer: stinginess and bad morals."
شرح الحديث :
The Hadīth indicates that a believer does not combine two blameworthy characteristics in his character; they are: stinginess and bad morals. What is understood from the Hadīth is that it is possible to find them in one who is deprived of the blessing of faith, because he lacks the faith that prevents bad morals. What is meant by the believer in which these two characteristics cannot be found is the true believer. If these characteristics are found in a person, it is indicative of a deficiency in his faith.
