Nasai

The intended meaning is that virtue is not restricted to any particular month; the poor can be fed at any time. Restricting it to the month of Rajab is not appropriate. To designate any month, day, or time from one’s own side and then consider it obligatory or superior is not correct. The reason for this is that it is neither the right nor the responsibility of any human being to specify particular times, days, or months and years for any act of virtue; rather, the determination of time for virtue is solely the right of Allah Ta‘ala. No one else has the authority to make changes in this regard. Furthermore, it is also necessary that the manner and quantity of virtue be exactly as prescribed by the Shari‘ah. Any excess beyond this will be considered an innovation (bid‘ah) and a human invention.
