Hazarat Ayesha (RA) narrates:
Another hadith states:
Following things should be borne in mind to avoid falsehood.
We should not tell a lie even in a joke. The Prophet (SAWS) has said:
This is our daily observation that people give full rein to their tongues in the matter of humorous talks to make others laugh, and do not hesitate to spread the tales and stories invented by friends or foes only for the purpose of getting some pleasure or for pulling someones leg. In fact it is due to this kind of entertainment and amusements and false acts that has created enmities and rivalries among us.
We should avoid exaggeration in praise. Some people when they praise somebody go to the extent of exaggerating and making false statements. For a Muslim it is necessary that when he praises somebody he should do it to the extent to which he knows about that man. He should avoid exaggeration and falsehood in showering the praises of the praised one, although he may be deserving of praises, for exaggeration is a kind of falsehood, which has been forbidden. To a person who was praising the Prophet, he said:
We should keep away from falsehood and deception in trade and financial dealings with others. Prophet (SAWS) said:
Never give false evidence while on oath, as it is perjury and a major sin. When a Muslim should stand up for giving evidence, he should state the truth unhesitatingly; regardless of the fact whether it is against his close friend or relative. No relationship or prejudice should deviate him from the right path, nor any greed or bribe should be able to make him waver in his stand.
Never break a promise given to someone. We should take special care to see that we keep our promises, be true to our words and not change our stand. It is a very sad state of affairs that among the Muslims the tendency of breaking promises and crossing limits has become very common, when our religion has termed the false promises as symbols of trouble.
