• مَّلْجَإ

Appears 3 times in the Quran.

1. 9:57 لَوْ يَجِدُونَ مَلْجَـًٔا أَوْ مَغَٰرَٰتٍ أَوْ مُدَّخَلًا لَّوَلَّوْا۟ إِلَيْهِ وَهُمْ يَجْمَحُونَ

   If they could find a refuge or cave or a place to enter into, they would certainly have turned thereto, running away in all haste.
   

2. 9:118 وَعَلَى ٱلثَّلَٰثَةِ ٱلَّذِينَ خُلِّفُوا۟ حَتَّىٰٓ إِذَا ضَاقَتْ عَلَيْهِمُ ٱلْأَرْضُ بِمَا رَحُبَتْ وَضَاقَتْ عَلَيْهِمْ أَنفُسُهُمْ وَظَنُّوٓا۟ أَن لَّا مَلْجَأَ مِنَ ٱللَّهِ إِلَّآ إِلَيْهِ ثُمَّ تَابَ عَلَيْهِمْ لِيَتُوبُوٓا۟ إِنَّ ٱللَّهَ هُوَ ٱلتَّوَّابُ ٱلرَّحِيمُ

   And to the three who were left behind, until the earth became strait to them notwithstanding its spaciousness and their souls were also straitened to them; and they knew it for certain that there was no refuge from Allah but in Him; then He turned to them (mercifully) that they might turn (to Him); surely Allah is the Oft-returning (to mercy), the Merciful.
   

3. 42:47 ٱسْتَجِيبُوا۟ لِرَبِّكُم مِّن قَبْلِ أَن يَأْتِىَ يَوْمٌ لَّا مَرَدَّ لَهُۥ مِنَ ٱللَّهِ مَا لَكُم مِّن مَّلْجَإٍ يَوْمَئِذٍ وَمَا لَكُم مِّن نَّكِيرٍ

   Hearken to your Lord before there comes the day from Allah for which there shall be no averting; you shall have no refuge on that day, nor shall it be yours to make a denial.
