Saint Kabir appeared on earth in 1398 CE and lived for 120 years before departing back to his orginal home 'Satlok' (Eternal Realm) in 1518 CE. During his lifetime on earth Sant Kabir did not acquire a wife.
There are many different opinions in the world. Some say that Saint Kabir's wife's name was Loi, while others say it was Lihini. These are baseless claims without any foundation. This falsehood has been spread by ignorant saints/scholars.
Kabir Ji did not have a wife. He had two foster children, a son named Kamaal and a daughter named Kamaali. Both of these children had died, and it was Saint Kabir who gave them the gift of life. Afterward, these children started living with Kabir Ji. He had no wife, nor did he have children of his own.
