وَاِذْ قَالَتْ طَّاۤىِٕفَةٌ مِّنْهُمْ يٰٓاَهْلَ يَثْرِبَ لَا مُقَامَ لَكُمْ فَارْجِعُوْا ۚوَيَسْتَأْذِنُ فَرِيْقٌ مِّنْهُمُ النَّبِيَّ يَقُوْلُوْنَ اِنَّ بُيُوْتَنَا عَوْرَةٌ ۗوَمَا هِيَ بِعَوْرَةٍ ۗاِنْ يُّرِيْدُوْنَ اِلَّا فِرَارًا ( الأحزاب: ١٣ )
Wa iz qaalat taaa'ifatum minhum yaaa ahla Yasriba laa muqaamaa lakum farji'oo; wa yastaazina fareequm minhumun Nabiyya yaqooloona inna buyootanaa 'awrah; wa maa hiya bi'awratin iny yureedoona illaa firaaraa (al-ʾAḥzāb 33:13)
And when a faction of them said, "O people of Yathrib, there is no stability for you [here], so return [home]." And a party of them asked permission of the Prophet, saying, "Indeed, our houses are exposed [i.e., unprotected]," while they were not exposed. They did not intend except to flee. (Al-Ahzab  : 13)

and when a group of them said, “O people of Yathrib (Madīnah), there is no place for you to stay; so go back.”And a group of them was seeking permission (to leave) from the prophet, saying, “In fact our homes are vulnerable,” while they were not vulnerable; they wanted nothing but to escape.
