Is it permissible to deposit money in a bank with interest if the intention is for good?

Question:

Is it permissible for me to put money in the bank to receive murabahah (cost-plus sale) on it, knowing that my intention with the profits is to distribute them in the ways of good, and so that this money does not remain idle?

Answer:

That is not permissible; because that is the very riba (usury or interest) that the scholars have explicitly prohibited, and the texts from the Sunnah indicate its prohibition. It is what is called a loan that yields benefit.
The intended benefit is the one that is stipulated or agreed upon, even if the intention of the one doing it is good; because Allah has forbidden riba (usury or interest) due to the harms and damages it causes to society in general and to the poor in particular.
It is possible for a Muslim to give money to a bank or others for the purpose of investment in an Islamic manner, such as mudarabah (a profit-sharing partnership); by placing his money in specific goods, which are sold on behalf of the owner of the money, and the profit is shared between them according to what they stipulated, such as equal division or otherwise. The contract of mudarabah (a profit-sharing partnership) is permissible by scholarly consensus (ijma'), provided it meets the conditions that the scholars have clarified in their appropriate places.
