Firstly: Giving What it is Worth
It is sufficient to pay the worth of the necessary amount - other than with charity of Fitr – out of need or for valid benefit. This is a narration from Ahmad, the choice of Ibn Taymiyyah, Ibn Baz, and Ibn `Uthaymin.
Secondly: Transferring the Charity from the Country of the Wealth
1. The residents having more right
For each town or community, the legal charity they pay has more right to remain for the needy among them. Abu `Ubayd ibn al-Qasim ibn Sallam quoted consensus on this.
2. The ruling of unconditionally transferring charity from one land to another
It is permissible to move it for a need or a benefit. This is explicitly mentioned by the Hanafis and Malikis, and it is a narration from Ahmad chosen by Ibn Taymiyyah, Ibn Baz, and Ibn `Uthaymin.
Thirdly: Investing the Wealth of Charity
It is not permissible to invest charity wealth. This is the chosen position of the International Islam Fiqh Academy as part of the Muslim World League, the position of Ibn `Uthaymin, and the verdict of the Permanent Committee.
Fourthly: Deception to Avoid Legal Charity
It is impermissible to try to avoid paying charity by manipulating the conditions to one's desires. It does not fall as an obligation through this. This is the position of the Malikis, Hanbalis, a group of the Shafi`is, Ishaq ibn Rahawayh, Abu `Ubayd al-Qasim Ibn Sallam, and it is the choice of Ibn Taymiyyah, Ibn al-Qayyim, and Ibn `Uthaymin.
