Sadaqah, especially Sadaqah Jariyah (ongoing charity), is among the greatest acts of obedience that draw us closer to Allah, but on condition that Sadaqah is given according to the teachings of Shari‘ah (Islamic law). It must be given from lawfully earned money and paid into the permissible channels, such as for the poor and the needy, or for building a Masjid (mosque) and the like.
(Part No. 2; Page No. 257) Associating the giving of Sadaqah with a particular time unspecified by the Shari‘ah, based on a belief of its merit, is not permissible. Consequently, if this Sadaqah is paid during Sha‘ban due to a belief in the sacredness of this month or any of its days, it will not be considered among the lawful Qurbahs (good deeds by which Allah's Pleasure is sought).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
