Are the widespread Sufi orders—such as the Naqshbandi, Qadiri, and Tijani—which have a continuous chain of transmission (sanad) back to the Messenger of Allah, peace and blessings be upon him, considered valid in the view of Islamic Sharia?

Allah sent His Prophet Muhammad (peace be upon him) with Islam, and our religion is based on monotheism and the rejection of polytheism, and following what Allah and His Messenger have permitted and avoiding what they have forbidden. Happiness lies in adhering to the Book of Allah and the Sunnah of His Prophet (peace be upon him), as did the Companions of the Prophet and those who followed them in goodness.

The Messenger (peace be upon him) must be the only role model. Nothing is worshipped by him except what he has legislated. What is lawful is what Allah and His Messenger have permitted, and what is unlawful is what Allah and His Messenger have forbidden. One must avoid innovations (bid'ah) and newly invented matters that appeared after the favored generations, for every innovation is misguidance, and every misguidance leads to the Fire.

Contemporary Sufi orders often contradict what the Prophet (peace be upon him) brought regarding pure monotheism and correct adherence. They vary in their deviation from the Sunnah, and some of them may even reach polytheism. The decisive factor is what the Prophet (peace be upon him) and his Companions were upon.

The criterion for distinguishing truth from falsehood is beneficial knowledge inherited from the Prophet (peace be upon him) and his Companions. Therefore, a Muslim must adhere solely to the path of the Prophet (peace be upon him) and receive his Sunnah from trustworthy scholars.

Allah Almighty says: "Say, [O Muhammad], 'If you should love Allah, then follow me, and Allah will love you and forgive you your sins.'" (Aal Imran: 31).

The Prophet (peace be upon him) said: "Indeed, whoever lives among you will see much disagreement. Beware of newly invented matters, for they are misguidance. Whoever among you perceives that, then he must adhere to my Sunnah and the Sunnah of the rightly guided Caliphs. Cling to it with your molars." (Narrated by At-Tirmidhi).

One must turn away from deviant paths and seek guidance in the Book of Allah and the Sunnah of His Messenger (peace be upon him). The scarcity of those who follow the path of truth does not harm a Muslim.
