Is the statement "Beliefs are based on divine injunction" correct, and if so, how is it permissible to act upon a weak hadith? And is seeking help from Allah's servants during a predicament considered shirk based on the weakness of the hadith reported regarding that, taking into account that Allah and His Messenger did not command it, and that angels do not possess the ability to help absent humans, and that seeking help from the unseen is forbidden, with the understanding that the act would not be shirk if the hadith were authentic?

Beliefs are not established except by evidence from the Quran, Sunnah, or scholarly consensus. The statement of a Companion, if it is not open to personal opinion and the Companion was not known to have taken information from the People of the Book, has the ruling of a Marfu' (a Hadith directly attributed to the Prophet), unless the Companion was known for narrating Isra'iliyyat (stories from Jewish or Christian traditions) like Abdullah ibn Amr ibn al-Aas.

It is not permissible to use a weak Hadith to establish any belief or legal ruling. The Hadith, "If one of you encounters a lameness in a desolate land, let him call out, 'Assist, O servants of Allah, may Allah the Almighty have mercy on you,'" is weak.

However, the Hadith is mawquf (attributed) to Ibn Abbas and was acted upon by Imam Ahmad ibn Hanbal. Some scholars have graded it as hasan (good). If the Hadith is authentic or hasan, its meaning is seeking assistance from the living present in matters they are capable of. The intended meaning of "servants of Allah" in the Hadith refers to the angels who hear and are able to respond with their Lord's permission. The Hadith does not indicate the permissibility of asking the dead or those who cannot hear or respond, as that would be polytheism (Shirk).
