Is it Sunnah to say Laa ilaaha ill-Allaah when parting from one’s friend?

Question

Praise be to Allah.

Firstly:

We do not
know of any saheeh (sound) or da’eef (weak) hadeeth which speaks of this
dhikr when parting or concluding a gathering. Hence persisting in it or
believing it to be a dhikr that is prescribed on such occasions is a bid’ah
that is be rejected, because the Prophet (peace and blessings of Allaah
be upon him) said: “Whoever does any action that is not in accordance with
our affair will have it rejected.” Narrated by Muslim (1718).

The scholars
have stated that singling out a particular time or place for an act of
worship, or a particular manner in which it is to be done, with no proof
from the texts, makes it a kind of bid’ah and innovation, in which case it
is called bid’ah idaafiyyah. It is prescribed in principle, but is rejected
because of the manner in which it is done. Acts of worship must be
prescribed in and of themselves, the manner in which they are done, the time
at which they are done and the number of times they are done, because Allaah
can only be worshipped in the ways that He has prescribed in His Book or on
the lips of the Messenger of Allaah (peace and blessings of Allaah be
upon him).

Al-Shaatibi
(may Allaah have mercy on him) said: Bid’ah, therefore, refers to a
fabricated religious way which competes with the way that is based on
sharee’ah, whereby following it is intended to go to extremes in devotion
and worship.

That also
includes adhering to certain ways and forms of worship, such as reciting
dhikr in unison, taking the day of the Prophet’s birthday as a festival, and
so on.

It also
includes adhering to a specific act of worship at a specific time for which
there is no basis in sharee’ah, such as always fasting on the fifteenth of
Sha’baan and spending that night in prayer.

Secondly:

It is
prescribed to end a gathering by saying that which was narrated by Abu
Dawood (4859) from Abu Barzah al-Aslami (may Allaah be pleased with him) who
said: The Messenger of Allaah (peace and blessings of Allaah be upon
him) used to say, when he wanted to leave a gathering: “Subhaanaka
Allaahumma wa bi hamdika, ashhadu an laa ilaaha illa anta, astaghfiruka wa
atoobu ilayk (Glory and praise be to You, O Allaah, I bear witness that
there is no god but You, I seek Your forgiveness and I repent to You).” And
he said: “It is expiation for whatever happened in that gathering.”

Classed as
saheeh by al-Albaani in Saheeh Abi Dawood.

It is also
prescribed for one of the people present to recite Soorat al-‘Asr when
ending the gathering, because of the report narrated by al-Tabaraani in
al-Awsat (5124) from Abu Madeenah al-Daarimi (may Allaah be pleased with
him) who was a companion of the Prophet (peace and blessings of Allaah
be upon him). He said: When two men of the companions of the Prophet
(peace and blessings of Allaah be upon him) met, they would not part until
one of them recited “By Al‑‘Asr (the time), Verily, man is in loss”
[al-‘Asr] over the other, then one would say salaam to the other.
Classed as saheeh by al-Albaani in al-Silsilah al-Saheehah (no.
2648).

Look at how
people have turned away from a proven Sunnah for the sake of the bid’ahs
that they have introduced, confirming the words of the Prophet (peace
and blessings of Allaah be upon him): “No people introduce a bid’ah but
something equivalent will be taken away from the Sunnah.” Narrated by Ahmad
(16522). Al-Haafiz said in al-Fath (13/253): Its isnaad is jayyid.

May Allaah
enable us and you to follow the Sunnah and avoid bid’ah.

And Allaah knows best.
