In the ancient book on Sufism, The Kashf al-Mahjub, written by Ali al-Hujwiri, we find this reference to the 10th c, CE Persian Sufi Abul Hassan Kharqani:

It is related that Abul Hassan said, “There are two ways, one wrong and one right. The wrong way is Man’s way to God, and the right way is God’s way to Man. Whoever says he has attained to God has not attained; but whenever anyone says that he has been made to attain to God, know that he has really attained.” It is not a question of attaining or not attaining, and of salvation or non-salvation, but one of being caused to attain or not to attain, and of being given salvation or not being given salvation.
