Can I still say "good luck" as a Muslim?

Islam rejects superstition

The Prophet Muhammad ﷺ said: "No 'Adwa nor Tiyara; but I like Fal." When asked what Fal is, he said: "A good word" (Sahih al-Bukhari 5776).

Tiyara means believing in bad omens. Islam rejects the idea that black cats, broken mirrors, the number 13 or walking under ladders bring bad luck. But the Prophet ﷺ liked optimism and kind words.

"Good luck" as a kind word

When most people say "good luck," they mean "I hope it goes well for you." That's close to the good word the Prophet ﷺ liked. Many scholars therefore say it's fine, especially with non-Muslim friends and coworkers.

Some scholars prefer to avoid it, because "luck" can suggest a power outside Allah's control. Both views exist, and using a more Islamic phrase avoids the question entirely.

The same goes for "lucky": saying "I was lucky" often just means "things went well." Many Muslims prefer "Alhamdulillah" (praise be to Allah), which gives the credit to the right place.

Better alternatives

• "May Allah make it easy for you."
• "InshaAllah it goes well."
• "I'll pray for you."
• "All the best!" or "You've got this!" for non-Muslim friends.

Superstitions to drop

• Knocking on wood to avoid bad luck.
• Lucky charms, rabbit's feet or "evil eye" beads worn for protection.
• Fear of Friday the 13th, black cats or spilled salt.
• Crossing fingers as if it changes the outcome.

Instead, Islam teaches you to say "Bismillah" before starting something and to trust Allah. For other everyday phrases, see Can I still say "bless you" when someone sneezes as a Muslim? and Can I still read my horoscope after becoming Muslim?
