The ruling on one who claims the permissibility of leniency and relinquishing obligatory religious duties under the pretext of considering benefits and harms?

Question:
Your Eminence, may Allah guide you. This questioner from Algeria says: We have a man who claims the permissibility of leniency and relinquishing obligatory religious duties under the pretext of considering benefits and harms. He cites as evidence for this the fact that a menstruating woman leaves off the ritual prayer and fasting, even though they are pillars of Islam. He also cites as evidence the fact that the Prophet (peace and blessings be upon him) left out writing "The Most Merciful, the Compassionate" and did not write "Muhammad is the Messenger of Allah." He also cites the fact that the ablution is left off for one who does not find water. What is the validity of these arguments?

Answer:
Answer: This is an invalid argument, and it is a deviation from the Book of Allah and the Sunnah of His Messenger (peace and blessings be upon him). This man must repent to Allah. He must announce his repentance from this delving into the rulings of Allah (Mighty and Majestic) without knowledge, or without insight, or following desire. It is not permissible for him to speak in this manner. If his words were accepted, the entire religion would be changed, and it would be said that the public benefit necessitates this. It would be said, "You do not pray because the public benefit necessitates that you do not pray so that the disbelievers do not mock you." It would be said, "You do not pay the obligatory alms so that it is not said that there are needy and poor people among the Muslims." This matter is never permissible. He must repent to Allah (Mighty and Majestic) and return to the truth and correctness. And it is obligatory to disapprove of him. Yes. The Messenger (peace and blessings be upon him) left out the writing. He did not prevent "The Most Merciful" such that it is not said "The Most Merciful, the Compassionate." He did not prevent this, nor did he remove the name from its origin. Rather, he only left out the writing. And his leaving out the writing does not indicate leaving out the name (Bismillah, in the name of Allah, Mighty and Majestic). Yes.
