Q: What is the ruling on using geometrical terms while making Du`a' (supplication), like asking Allah to make one as straight as a "straight line", or causing him to enter in the "circle" of His mercy, or the "circumference" of the righteous people, or to hail him with a "perpendicular line" of light? Is it permissible to make Du`a' in such a manner, or does this fall under the category of
Bid`ah (innovation in religion)?
This Du`a' contains words which are not compatible with Allah's Purified Shar` (Law) like asking Allah to hail one with a perpendicular line of light. Such Du`a' must be avoided. One has to supplicate to Allah using the various formulas of Du`a' found in the Qur'an or authentically reported in the Sunnah (whatever is reported from the Prophet). He must avoid using any formula of Du`a' incongruous with the Qur'an and Sunnah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
