Cursing in Islam is subject to specific guidelines. General curses against evildoers and disbelievers are permissible, while cursing individuals is disputed among scholars. The Prophet (peace and blessings of Allah be upon him) discouraged cursing specific sinners, emphasizing mercy and repentance.

When people say ‘good luck’ and the like, as a kind of supplication for the person to whom it is said, and wishing him well, there is nothing wrong with that, as is obvious. In fact, it is praiseworthy because it is a kind of supplication for good and wishing the Muslims well. But one should not wish or pray for bad luck for a Muslim, because this involves transgression and enmity towards one’s brother in faith.

There does not seem to be anything wrong with this phrase, and there is nothing to dictate that one should be strict about it or tell off anyone who says it. But saying “May the angels pray for forgiveness for you, and the like,” is more appropriate and is better.

Giving a name such as this to this type of food is like a metaphor, and there is no reason to think that it is sharing a name with Allah, may He be exalted.
