Is it possible to adopt the concept of mafhum al-mukhalafa (inference by contradiction) from the Hadith: "Whoever introduces into this matter of ours that which is not of it, it is rejected," to infer the legitimacy of adding to acts of worship? And does the Prophet's approval of the Companion who added to the remembrance after bowing (rukūʿ) fall under this concept? And did the Prophet approve only the verbal addition or the principle of addition in general? And is it permissible to create a new supplication for rising from bowing, following the example of that Companion? And is there a precedent or a proof for this action?
An increase in praise (Al-Hamd) after rising from bowing (ruku') is not a reprehensible innovation, because prayer is based on glorification (tasbih), magnification (takbir), and recitation of the Quran. The Prophet, peace and blessings be upon him, approved of one who increased praise after bowing, and this does not contradict the prohibition against innovation in religion. Rather, it falls under the category of praising Allah the Almighty, which is permissible in prayer. This should be understood in light of the Sharia evidence that prohibits innovation.
