I invite you to have respect for those people who have the right that they should be respected, those between whom there is an agreement (of protection) for you. For the land in which you are living is such that there is an agreement between you and them. If this were not the case they would have killed you or expelled you. So preserve this agreement, and do not prove treacherous to it, since treachery is a sign of the hypocrites, and it is not from the way of the Believers. And know that it is authentically reported from the Prophet that he said:
"Whoever kills one who is under an agreement of protection will not smell the fragrance of Paradise."
Do not be fooled by those sayings of the foolish people, those who say "Those people are Non-Muslims, so their wealth is lawful for us (to misappropriate or take by way of murder and killing)." For by Allah - this is a lie. A lie about Allah's Religion, and a lie about Islamic societies.
So we may not say that it is lawful to be treacherous towards people whom we have an agreement with.
O my brothers! O youth! O Muslims! Be truthful in your buying and selling, and renting, and leasing, and in all mutual transactions. Because truthfulness is from the characteristics of the Believers, and Allah - the Most High - has commanded truthfulness - in the saying of Allah - the Most High:
"O you who believe - fear and keep you duty to Allah and be with the truthful."
And the Prophet encouraged truthfulness and said:
"Adhere to truthfulness, because truthfulness leads to goodness, and goodness leads to Paradise. And a person will continue to be truthful, and strive to be truthful until he will be written down with Allah as a truthful person."
And he warned against falsehood, and said:
"Beware of falsehood, because falsehood leads to wickedness, and wickedness leads to the Fire. And a person will continue lying, and striving to lie until he is written down with Allah as a great liar."
O my brother Muslims! O youth! Be true in your sayings with your brothers, and with those Non-Muslims whom you live along with - so that you will be inviters to the Religion of Islam, by your actions and in reality. So how many people there are who first entered into Islam because of the behaviour and manners of the Muslims, and their truthfulness, and their being true in their dealings.
