The hadith advises obeying religious and political authority, even if a black slave is the leader. It warns against religious innovation and emphasizes following the teachings and traditions of the Prophet Muhammad and the Rashidun caliphs. True religion, science, and governance work best when aligned with divine laws and principles of social harmony.

2. ”I advise you to fear Allah and obey, even if a black slave
becomes your leader. Those of you who live long enough will
see great controversy, so adhere to my Sunna and the Sunna
of the rightly guided caliphs. Cling to them stubbornly.
Beware of newly invented matters in religion, for every
invented matter is an innovation. Every innovation is going
astray, and every going astray is in Hellfire."
[Tirmidhi]
The Arabic word translated here as "fear of Allah" is taqwa.
Derived from wiqaya (protection), taqwa means to be in the
safekeeping or protection of Allah.

3. This has two aspects. The first is that believers fear Allah and
obey Him by observing His commands and prohibitions.
To be under the safekeeping of Allah, true religion and science
should be combined, for they are two expressions of a single
truth. According to Muslim scholars, the universe is "the
Created Quran." where Allah's laws issuing from His Attributes
of Will, Destiny, and Power are operative. The Quran, the
collection of Divine laws issuing from Allah's Attributes of
Speech, is "the composed universe" or "the universe in words."

4. The second aspect is that, by studying nature and life and
discovering the laws of Allah that control them, people acquire
scientific knowledge and order their lives. Science cannot be
established if people do not discover these laws.
The believers should not disobey their government without
justifiable cause. Without a leader, a community is like a broken
rosary whose beads have scattered everywhere. Such a situation
of social and political conflict usually results in anarchy and
destruction.

5. The hadith also points out a truth that even modern
democracies have proven unable to grasp: no racial
discrimination. It is clearly stated that an emancipated black
slave can lead the Muslim community. This was not only a
theoretical assertion, but was testified to by the numerous and
great black administrators and scholars who were respected and
obeyed.

6. Allah's Messenger also draws attention here to his Sunna. As
he is the most excellent example for all aspects of life, believers
are to follow his example until the Last Day. Such adherence
guarantees that Islam retains its original purity. Any deviation
will result in social and doctrinal splits and new importations
into Islam, the religion perfected by Allah. Adherence to the
way of the first four caliphs also guarantees of Muslim unity
and Islam's maintenance.
