﴿ قَالُوا۟ طَٰٓئِرُكُم مَّعَكُمْ ۚ أَئِن ذُكِّرْتُم ۚ بَلْ أَنتُمْ قَوْمٌۭ مُّسْرِفُونَ ﴾

“[The apostles] replied: “Your destiny, good or evil, is [bound up] with yourselves! [Does it seem evil to you] if you are told to take [the truth] to heart? Nay, but you are people who have wasted their own selves!””

The sense of the statement: قَالُوا طَائِرُ‌كُم مَّعَكُمْ (They said, "Your bad omen deeds.' The word: طَایٔر (ta'ir) essentially denotes bad omen or misfortune and, on occasions, it is also used to refer to the effects of misfortune, that is, wretchedness. Here, this is what it means. (Ibn Kathir, Qurtubi)
