omar bin alkhattab may god be pleased with him said god does not bestow a blessing upon a servant except that you will find someone who envies him for it. if a man were more upright than a cup you would find someone who slanders him.
وقال عمر بن الخطاب رضي الله عنه ما أحدث الله بعبد نعمة إلا وجدت له عليها حاسدا. ولو أن امرأ كان أقوم من القدح لوجدت له غامزا .
