It is not permissible to deal with bribes, either accepting them or giving them. This is a major sin in Islam. Exceptional cases are: 1- taking one’s right, 2- removing or alleviating wrongdoing, and 3- giving money to workers or offices to go to the official bodies and do what is needed.

If money was given to a person for a certain purpose, then he does not have the right to spend it on anything else, or to give some of it to anyone, except with the permission of those who gave it to him. Additionally, he must return whatever is left over of it, if there is anything left over.

Giving gifts is something that is encouraged, because it softens hearts and strengthens the bonds of Islamic brotherhood and sisterhood. Bribery is something that is forbidden, because of what it leads to of wrongdoing and transgressing people’s rights, and reinforcing selfishness. The difference between them is clear.

1- If your father’s aim was to achieve a specific purpose, then you do not have the right to spend the money on anything else, even if he did not emphasise that it was a trust and was only to be used for that purpose. 2- But if he was only advising you [as to how to spend it] and he would not mind if you spend it on something else, then there is no blame on you in that case.

Waqf is an act of worship which is recommended in Islam (mustahabb). The one who establishes the waqf should be one who has the authority to dispose of this wealth. The property given as waqf should be something from which ongoing benefit may be derived whilst its original essence remains. It is obligatory to act in accordance with the wishes of the one who set up the waqf so long as it does not go against the Shari`ah.

When the property is found, the finder should not take it unless he is certain that he can be trusted to keep it and is able to make the necessary announcements until he finds the owner.

Lending in Islam is prescribed in the Quran and Sunnah, and by scholarly consensus. Some scholars view that lending is obligatory in Islam quoting the verse “… and refuse al-ma'un (small kindnesses).” [Al-Ma’un 107:7] as evidence.

There is nothing wrong with opening current accounts - without interest - in riba-based banks, if there is a need for that and there are no Islamic banks that could meet the customer's needs without much trouble and difficulty.
