Nasai

1539. Commentary:
➊ That is, seeking Allah’s refuge, protection, and safety from all kinds of confusions, worries, and sorrows, etc. The only amulets (ta‘widh) established by the Shari‘ah are those mentioned ahead. As for those people who write something and hang it around their necks or tie it on their arms, this is not established from the teachings and guidance of the Messenger of Allah (sallallahu alayhi wa sallam); therefore, one should avoid this. Moreover, there are some who write words and phrases of disbelief (kufr) and polytheism (shirk) in these amulets, which is nothing but a transaction of purchasing Hell. May Allah protect us from them.
➋ There are other ahadith on this subject and meaning; it would be more beneficial to look at all of them.

Benefits and Issues:
Our esteemed researcher has declared the mentioned narration weak in its chain of transmission (sanadan da'if) and has further written that there is a corroborating narration (shahid) with slight variation in wording, which is narrated with a sound chain in Sahih Ibn Khuzaymah.
See the research and verification of this hadith.
In addition, other researchers have also declared it authentic (sahih).
This shows that although the mentioned narration is weak in its chain, it is acceptable as evidence (hujjah) due to other supporting narrations (shawahid).
For further details, see: (al-Mawsu‘ah al-Hadithiyyah, Musnad al-Imam Ahmad: 1/290, 291 and Sunan Ibn Majah, verified by Dr. Bashar ‘Awwad, Hadith: 3844)

(1) The purpose of seeking refuge is protection; that is, O Allah! Keep me safe from these things.

(2) "The most abject age" refers to the stage in which a person's faculties fail him. A person becomes completely dependent, neither able to benefit himself nor anyone else; that is, the most severe form of old age.

(3) By the trial of this world is meant misguidance, for which the punishment of the grave is incurred.

For details, see the ahadith: 5445, 5447, 5448.

(1) Every person should always supplicate before Allah, the Mighty and Majestic, to be protected from the destruction and ruin of his family, wealth, and possessions, and from their calamity and trial.

(2) This blessed hadith indicates that the supplication and imprecation (bad-dua) of the oppressed is accepted; therefore, every intelligent, wise, and sensible Muslim man and woman should make every effort to obtain the supplication of the oppressed and to avoid their imprecation. Furthermore, one should supplicate to be protected from becoming either an oppressor or oppressed.

(3) From this blessed hadith, it is understood that reciting the mentioned remembrances (adhkar) and supplications, and adhering to them at the beginning of a journey, is recommended (mustahabb). Many ahadith have been narrated regarding this. Some scholars have compiled these remembrances in book form, such as Imam Nawawi rahimahullah in his “Kitab al-Adhkar.”

(4) “Returning sorrowful” means that I return unsuccessful in my objective, feeling grief.

(5) “Loss after benefit”—these are comprehensive words that encompass every benefit and harm, and all good and evil; for example: disbelief after faith, illness after health, and poverty after wealth, etc.

(6) “The imprecation of the oppressed”—the intent is that I do not wrong anyone so that I am not subjected to their imprecation.

(7) “An evil sight among family and wealth”—that is, that no harm befalls them in my absence.
