Shaikh Abdul Qadir Jilani, in the collection of his sermons known as “Purification of the Mind,” makes the following observations about a very important transition which may come by the blessings of the Almighty.

In the beginning, when faith is still weak, the person says “There is no God save Allah,” but at the end, when faith has become strong, the person says, “There is no God save You,” as he addresses One (mighty and glorified is He) who is present and seen. This is a hidden matter, a total secret, one of His favours. Therefore the Prophet (Allah’s prayer and peace be on him) said, “There are days in your lifetime in which Allah (mighty and glorified is He) confers favours, so avail yourself of them.”
