(ف) لَغَبَ يَلْغَبُ لُغُوْبًاlaghaba yalghabu lughūban: to become tired, to be worn out.
لُغُوْبlughūb: fatigue, weariness. Twice in the Quran, both times with a negation — once in affirming the power of God and once in describing Paradise: ﴿وَمَا مَسَّنَا مِنْ لُّغُوْبٍ﴾ (Qāf 50:38) and ﴿لَا يَمَسُّنَا فِيْهَا نَصَبٌ وَّلَا يَمَسُّنَا فِيْهَا لُغُوْبٌ﴾ (Fāṭir 35:35).
