Is breaking a promise one of the signs of hypocrisy?

Question:
A man promises his neighbor to attend a wedding feast, for example, but does not attend. A man promises his children to buy this or that but does not fulfill it. A man promises his neighbor to attend a wedding feast but does not attend. A man promises his children to buy this or that but does not fulfill it. A man speaks to another, his tongue runs freely with him, and he makes his speech pleasant, but his heart holds something else. Is any of this considered one of the signs of hypocrisy?

Answer:
There is a distinction here. The Prophet (peace and blessings be upon him) said regarding the hypocrite: "The signs of the hypocrite are three: , and when he disputes, he is unjust, and when he makes a covenant, he betrays it." Therefore, a Muslim must avoid the characteristics of the hypocrite and not be like him. If he makes a promise, he should strive to fulfill it. If he is entrusted, he should not betray the trust. If he promises his brother a feast, he should strive to honor his invitation. However, if the one who was promised is delayed, meaning the questioner’s confusion, if he is delayed, he may have an excuse. But if you promised him, you are the one who is responsible for this. As for him, if he promised you but failed to show up, he may have an excuse. Likewise, with your children, strive to teach them truthfulness and be truthful with them so that they do not accuse you of lying and become accustomed to you lying. They learn from you and say, "Ask for permission to lie." But truthfulness is always the rule, except with the wife, where you have an excuse. If it is with the wife, you may lie to her for the sake of benefit, and she may lie to you for the sake of benefit, in matters concerning only the two of you, not extending beyond you. I said, "I bought this, and I bought that, and I did such and such," to ward off her harm so that she does not hurt you. There is no harm if you lie to her and did not do it. She likewise says, "I will do it, if Allah wills," and "I will do it," and "I will do it," and "I will not delay in obeying your orders." She offers pleasant words even if she lies, until things are right with you and the situation proceeds well. Do not say, "I will never do it," or "I will not give you," or "No, no, no." Use pleasant words, even if you lie, but only in matters concerning the two of you. There is no shame and no need to lie to her regarding other people.
