The ruling on excessive bending in prostration

Question : The questioner says: I hope you will inform me about the following characteristics in prayer: did they come from the Messenger of Allah (peace and blessings be upon him) or not? They are: placing the hands on top of the feet while standing. Second, excessive bending while standing. Third, excessive stretching while in prostration. As for placing the hand

Answer : the right one over the left, this has been established by hadiths from the Prophet (peace and blessings be upon him), and the hadiths regarding this are numerous. As for where the hands should be placed? There is no authentic hadith that specifies this matter clearly. The best evidence for this is the hadith of Wa'il ibn Hujr, that the Prophet (peace and blessings be upon him) used to place them on his chest.
This is the best hadith reported on this matter, despite the discussion among the scholars regarding it. As for the hadith that he placed them below the navel, it is a weak hadith. Therefore, the stronger position in our view is that it is better for a person to place them on his chest. I mean. May Allah bless you, O son of 'Abd.
As for excessive bending while in bowing (ruku'), if it reaches the level of bowing, then standing does not suffice. If it is in an obligatory prayer, his prayer is invalid, unless there is an excuse for the person. If it is less than that, it is also contrary to what is prescribed, for the apparent evidence indicates that the one standing should be upright and straight, and not bend his neck or his back. Some jurists even say it is disliked for his beard to touch his chest; it is disliked for his beard to touch his chest. In any case, this opinion, whether it is correct or not, but I clarify that it is better for a person to be upright. As for the third point in his question.
It is excessive stretching during prostration. This is also contrary to the Sunnah, for those who described the prayer of the Prophet (peace and blessings be upon him) did not say that he stretched his back in prostration, as they said he stretched his back in bowing. Rather, what is prescribed in prostration is for a person to raise his belly from his thighs and elevate his back, not to stretch it as some people do.
