What is the correct understanding of the hadith concerning tying the beard, and what is the ruling on tying it without superstitious reasons, taking into account what the questioner mentioned about avoiding harm at work and so forth?

Scoffing at Muslims from disbelievers is expected, but from Muslims, it is dangerous, especially if it relates to the rulings of the religion.

Allah Almighty says: {The hypocrites are apprehensive that a Sūrah should be sent down about them, informing them of what is in their hearts. Say, “Scoff! Allah will bring to light what you apprehend.” And if you ask them, they will surely say, “We were only jesting and playing.” Say, “Was it at Allah and His verses and His Messenger that you were scoffing?” Make no excuse; you have disbelieved after your belief. If We pardon a group among you, We will punish another group because they were criminals.} (At-Tawbah/ 64-66). Scoffing at the verses of Allah or His laws is disbelief.

The Hadith prohibiting tying the beard: On Ruwayfi’ ibn Thabit, may Allah be pleased with him, he said: Indeed, the Messenger of Allah, peace and blessings be upon him, said: (O Ruwayfi’, perhaps life will be prolonged for you after me, so inform the people that whoever ties his beard, or wears an amulet, or cleanses himself with animal dung or bone, then Muhammad is disavowed from him.) Narrated by Abu Dawud (36) and An-Nasa’i (5067) and authenticated by Al-Albani.

Scholars’ interpretations of tying the beard: - Imitating the Persians in wars out of arrogance. - Fidgeting during prayer. - Styling and curling the beard out of luxury.

Based on this, there is no harm in tying the beard for the reason mentioned, and it is not included in the prohibition stated in the Hadith.
