أَيَا صَاحِبَ الدَّارِ، أَجِبْ
O resident of the house, respond.
هَيَا رَفِيقِي، أَقْبِلْ
O my companion, turn toward me.
Ayā and hayā are originally assigned to calls directed toward distant addressees. Their extended sound naturally suits calling across distance, but literary choice is not determined solely by geography.
In a phrase such as “ayā mawlāya,” the person may stand nearby while the chosen form suggests lofty status. Context and the relationship between speakers remain decisive.
