'Abdullah ibn 'Amr said, "Abu Mas'ud, what did you hear the Messenger of Allah, may Allah bless him and grant him peace, say about 'People who make false claims?" He replied, "I heard him say, 'A bad mount for a man' and I heard him say, 'Cursing a believer is like killing him.'"
Hadith Commentary: Sayings from Al-Adab Al-Mufrad 763
This narration from 'Abdullah ibn 'Amr through Abu Mas'ud al-Ansari contains two profound teachings from the Prophet Muhammad (ﷺ) concerning grave moral transgressions.
The Nature of False Claims
The expression "a bad mount for a man" employs a powerful Arabian metaphor. Just as a poor riding animal fails its rider, leaving him stranded or endangered, false claims destroy a person's spiritual journey. The scholar Ibn Hajar al-Asqalani explains that falsehood corrupts one's religion and worldly affairs, making it an unreliable vehicle for reaching virtuous destinations.
Al-Nawawi comments that this includes all forms of deception: false testimony, lying about visions or miracles, and fabricating religious knowledge. Such behavior indicates weak faith and corrupt character, as truthfulness is the foundation of prophethood and the path of the righteous.
The Gravity of Cursing Believers
The second statement equates cursing a believer with killing him. Imam al-Qurtubi elucidates that while literal killing destroys worldly life, cursing aims to destroy a believer's spiritual connection with Allah. A curse invokes Allah's wrath upon another Muslim, essentially wishing them eternal harm.
Ibn Rajab al-Hanbali notes that this severe warning reflects Islam's protection of Muslim honor and brotherhood. Just as physical murder violates the rights of creation, verbal aggression through curses violates the sanctity of faith. The believer's heart should be filled with mercy, not malice.
Practical Implications
These teachings emphasize the sacredness of truth and the inviolability of Muslim honor. Scholars derive that Muslims must guard their tongues against falsehood and harmful speech. Al-Ghazali reminds us that the tongue can either be a means of great reward or severe punishment, thus requiring constant vigilance and discipline in speech.
