Ishq

Ishq or išq (Arabic: عشق‎‎, Urdu: عشق‎, Persian: عشق‎‎, Central Kurdish: عیشق‎) in classical Persian, literally means 'love'. Ishq does not appear in the Quran, which instead uses the verb habba (حَبَّ) and its derivatives, for example the noun hubb (حُبّ). Moreover, in Modern Arabic the relevant terms dominantly used are: habba and its derived forms hubb, habib, mahbub, etc. The word is derived from ʿashiqah, a vine: the common belief is that when love takes its root in the heart of a lover, everything other than God is effaced. The term "Ishq" is excessively used by Sufis in their poetry and literature to describe their selfless and 'burning love for Allah'. It is the core concept in the doctrine of Islamic mysticism as it is the key to the connection between man and God. Ishq itself was the basis of 'creation'.

In the most languages such as Dari: eshq; in Pashto: eshq‎; in Somali: caashaq or cishqi; in Turkish: aşk and in Azerbaijani: eşq, in modern Persian as ešq or eshgh عشق, it literally means "love". ešq (عشق) used in Persian and Arabic (ʿišq), may have an Indo-European origin and may be related to Avestan iš- "to wish, desire, search", aēša- "desire, search", išaiti "he wishes", išt "wished for, beloved", išti- "aspiration, aim", and suggests that it derives from *iška. Avestan iš- is cognate with Sanskrit eṣ- "to wish, strive for, seek", icchā- "wish, desire", icchati "seeks for, wishes", iṣta- "beloved, sought", iṣti- "search, desire", Pali icchaka- "wishing, desirous". Note also that this word exists in Middle Persian in the form of išt "desire", as attested by Farahvaši.
