﴿ وَلَمَّا جَهَّزَهُم بِجَهَازِهِمْ قَالَ ٱئْتُونِى بِأَخٍۢ لَّكُم مِّنْ أَبِيكُمْ ۚ أَلَا تَرَوْنَ أَنِّىٓ أُوفِى ٱلْكَيْلَ وَأَنَا۠ خَيْرُ ٱلْمُنزِلِينَ ﴾

“And when he had provided them with their provisions, he said: "[When you come here next,] bring unto me that brother of yours from your father's side. Do you not see that I have given [you] full measure and have been the best of hosts?”

'Bring me a brother of yours from your father, since universal meanings that are attached to deeds can only be comprehended by that [rational] faculty. Know also that for those beloved [of God] their unveilings precede their [spiritual] efforts. Thus they teach their faculties the divine precepts and rulings and direct them after the arrival, even if their souls should be reassured before that [arrival]. As for the provision with which he equipped them is a small measure of particulars which they are able to comprehend and work with.
